Reproducing missing SPID

[1966 K10]

I am also trying to reproduce the missing SPID on my 66 K10 suburban. I could not locate the build sheet in the mat or seats so want to see what was on it from the factory. Its fairly all original with the exception of the rear end which was swapped at some time.

What I was wondering is if there was a specific order of the options listed on the spid. On later ones Ive seen the options seem to be all over the place with the paint and interior options usually on the bottom of the columns. Anything specific to 1966 spids? Different depending on plant?

Here is a list of known options for my burb.

K1406

C60 - 4 SEASON AIR COND
Z53 - AMMETER-OIL GAUGE
V74 - HAZARD WARNING SWITCH
F76 - FRONT WHEEL LOCK HUBS
Z62 - CUSTOM GROUP
A59 - THIRD SEAT
M20 - 4 SPD TRANSMISSION
K24 - CLOSED ENG POS VENT
L32 - 283 CU. IN. V-8 ENG
V76 - TOW HOOKS




The front sits SUPER high, is there any way to tell if they are HD front springs? How many leaves in a HD rear spring? Would Z61 also be listed? The engine has the closed PCV setup, is there a code for that or was it standard on all 283 v8s in 66?

Is there anything else I can visually confirm as a option over standard?

Here are a few pics

still looking for the correct burb ECL codes but this is what I have so far.

I would like to verify the AMP output of the alternator, not sure if there are any tell tale signs for HD battery and will check the glass to see if it is soft ray. Will also check the shocks to see if they are still original or swapped out.

In later burbs HD cooling and Soft Ray were standard with A/C were there any other "combined" or option bundles known for 60-66 trucks?

You'll be able to see the stamping on the alternator if you take it off and clean carefully.

Your going to need to hunt up all the spid sheets from that assembly plant you can find to get the correct order of things. ECL codes you'll find once you start researching those spids. Air conditioning in your truck was most likely a dealer option for K series, not factory installed so it would not be on the spid if thats the case. With AC you get the 42 AMP Alternator . HD battery should also mean you have the heavy duty starter. Check the number and date stamped in the starter housing. With all of these options a build sheet would tell you everything.

Ill clean and check the alt and starter.

Is there any way to tell factory A/C install vs. dealer? Most dealer installs Ive seen in burbs were under dash units.

Lucky for me when the PO installed a radio under the dash (leaving the factory radio delete plate and dash intact) they moved the ash tray under the glove box.

Ive checked under the mats and behind every seat top and bottom with no sign of a build sheet. The glove box door does have the outline of where the spid originally was but that is it.

[60-66]

Well , this leads to the question then , DID they install In Dash AC in the K series trucks or not AT the factory ? Data book does not list it for any K series as an option. Only in C series. The complete "in dash AC system" WAS offered as a Dealer install under accessory number 986443 which the accessory book does list for 283 C and K series. This is why I say researching spids on a K series might turn up proof they did this. Ive seen several K series trucks with AC including owning a 1965 K10 Suburban with AC. My point being though , is your spid your trying to reproduce may not have ever had the AC on it ? Thats the question.

Ok, I may be way off on this one as I've never owned a factory a/c truck before, but dealer installed a/c should show evidence of a hand cut hole for the in-dash bezel, right? Factory installed a/c began with a dash that had been die-cut for the purpose, no? In other words, pull your dash bezel off and look at the hole. Like I said, I may be wrong on this detail, but I seem to remember others who have had a/c equipped trucks mention this.
P.S. - Of course, the entire dash may have been replaced at some point in it's past, but it's a place to start looking.

Edit: - I did some quick searching and yes, I was correct about the cut-outs. There are also other methods of telling factory installed air from dealer add-on. Check this thread here: http://67-72chevytrucks.com/vboard/s...d.php?t=579863

Thanks guys, a lot of detective work to do. I was not aware that the in dash unit could be installed at the dealer. I was able to give it a quick look over last night and noticed the starter was missing and the alt has a lot of ashy surface oxide so will have to be removed to be cleaned.

I just received my NOS ign switch, uncoded lock cylinder and uncut keys, NOS horn ring and truck button and a friend donated a cherry steering wheel with no cracks and super nice paint.

I plan on cleaning it out more and remove the PO add on radio, return the ash tray to the correct position, install the ignition and while Im there carefully remove the center vent to look for hand cuts.

I noticed that burbs came with 8.50x15 tires, anyone know what the equivalent modern sizing? I have a set of 16x5 rims that I was going to use but looking at the options list it seems that it would have been a 16x6 wheel so guess thats out.

Another question, the glove box door has no hardware and I dont see what is missing. Could someone post what mounting pieces are needed to attach the door to the body? Are these reproduced or any good source? Looks like I need another silver door trim too as the original was broken and I only have one piece.

Last one, I thought I read about Packard ignition wires being factory are these date coded original wires?

Also the firewall for factory installed A/C would have been die-cut and dealer installed would have been hand cut. Here is good thread on dealer installed A/C. http://67-72chevytrucks.com/vboard/s...d.php?t=559436 Here is thread with some good pictures http://67-72chevytrucks.com/vboard/s...d.php?t=414039

[1966 K10]

So unless someone tells me otherwise Im gonna call it dealer install.

-Lower nut/bolt on cross member instead of rivet
-Dash looks rough, corners and lower cutout look different than pic of stamped dash.
-Color of control and vent assembly is fawn (64-65) not dark fawn (66)

These are the things I can confirm with exception being the tow hooks.

1966 K 10 wheels are :

15x5 1/2

16x5

17.5x5.25

All are 6 lug.

Wheels are dated in the center next to the size. 1966 on back will not have a code by the valve stem.

Yes those appear to be the original plug wires,

That's a really cool looking truck, i would like to see some side shots of it.

[1966 K10]

Sorry no recent side shots other that these from the PO before I got it. Its pretty beat with a huge dent on LT door and crushed rocker on the RT side

[Bad4wd]

Nice Fine,
I've got the same closed pcv sys. and upper rad. pipe you got on my 66. But change it to a open sys. and a 64-65 upper rad. pipe design.
I already change the upper rad. pipe back to the original like yours and need a pic of your pcv sys. behind the carb. and under the air cleaner to see the hose routing.

Thanks, Dave....

[1966 K10]

Ill try to get some more pics for you next time I work on it.

[1966 K10]

Here is a shot of the PCV setup. I have no idea what that large tube to the manifold goes to as it was not hooked up and looks to have a later clamp

[1966 K10]

A few dash pics and radiator cross bar detail

[1966 K10]

Im wondering about one thing, today I started degreasing the engine and right below the manifold above the waterpump the block is painted blue. Replacement engine? Also the ram horn exhaust manifold has air theaded bosses which are plugged, engine conversion rpo?

Thought I got pics of the plugs and blue but not on the card, Ill get some next time.

All engines built for 1966 Fremont usage had all of the California-Required exhaust emissions equipment on them. Usually that meant RPO K19 - Air Injection Reactor System, or "AIR", or "smog pump". If it was being delivered to a CA Dealer, then it was good to go. If it was going to a non-CA Dealer then it was "converted" by the Fremont Plant. RPO Z20 was the conversion option and it stripped the smog pump stuff off. Sounds like yours went out of state, hence the factory-installed manifold plugs.

Anyone know what these initials might mean? 168,639 or 68,639????

[The Rocknrod]

Means it was driven = miles.

It's a tough row to hoe the truth. But do it.
It will give you integrity either way, it is what it is and you (personally) will have integrity for it.
Unless of course you want to insist it is a roller rocker V-8. . . *************** .

So what do you think?

[1966 K10]

Just saw this today on a FB thread, anyone have a source for these or any reviews on performance?

Thanks, for the pic behind the carb. I get it, helps me bring my truck back to factory.
You need to degrease the eng. and get the # off the rear and pass. Frt side eng. block. The will give a lot of information.

Thanks, Dave...
