Anyone have this original in-bed spare tire carrier mounted?

[71CHEVYSHORTBED402]

If I understand you right, Suburban had a service 10? Didn't know that, I thought that was marked for a c-10, course it doesn't say fleetside etc like the 1023, which doesn't show for 1971, but it's likely correct anyway. Fun!

Here's the 1022, which shows for 69-72 service 10-30. Couldn't tell you what it's for, but I bet it works. Manual says cut to fit.: http://shop.docrebuild.com/1955-1991...GM3991022.aspx

Edit, I found this illustration for a 1022. http://www.discontinuedspares.com/in...ucts_id=435385

We pretty well beat this to death and thanks to all for the information. Especially the walking GM encyclopedia in SS. Still curious if the top and bottom screws differ, and if anyone believes this is an original bolt for the carrier. It may be for carrier under the bed. It's definitely a 67-72 serv 10-30 part.

Pics I have found here in the forum.

that origonal bolt... a carrige bolt... is what Gm called for. I got almost exactly the same bolt from ACE. same threads as a lug nut for a half ton. interesting that it calls for two of them. maybe three or even six for my 72c10. with my luck. interetsting

Mine has carriage head bolts in the floor,same size and length as the rest of the floor bolts.I don't have the bolt to hang the spare though.
Strange,it also has the under bed spare hanger.

Makes sense they'd reuse the bed bolts for the bottom. That carrier looks awfully close to the wheel housing, but if I recall, mine was the same and likely factory. Apparently the tire rests a tad against the wheel housing?

Holy crap 100% Chevy - those photos are end of story as far as the in-bed spare topic.

In my own mind I am a better man for having seen those pictures, no joke.

Thanks for posting and will be interested to see if anyone can top your post with that original SPID and photo of the factory installation.

I had a funny (to me anyway) thought - where someone installs four (4) spare carriers in each of the four corners of their bed; and puts a fifth one under the bed... rolling with five spares - take that triple A!

I don't have a good picture of mine, but it looks just like the rest of these so it must be original. I wouldn't mind a 2nd one, a 2nd spare. They are a great place to store your tire chains, plus often it's easier to change tires than install chains.

I'm glad my pictures helped.
Ya'll gotta remember that back then,these trucks used relatively small tires compared to today.
I have P235-70-15 on it now,which are a little too wide for the stock rims width.
When I was a young red-neck type deer hunter,I drove a 63,C-10.I always had 2 re-capped mudgrip tires in the bed to use in deer season and street tires for the rest of the year.It was a common thing down here.

I took a couple pictures of my set-up today:

I just have a piece of all-thread for a bolt



The tire is held on with these spacers and wing-nut:



Like this:



It works for me!

[71CHEVYSHORTBED402]

That's bolt set-up is nice Pritch.

[71CHEVYSHORTBED402]

It does appear the screws for the top are the same as that for the spring for the jack handle behind the door (5/16" x 3/4"). Might be shorter however. Just received a carrier and the top holes are 3/8". So unless I'm mistaken that calls for a 5/16" thread.

That's my report.

So quick questions regarding this spare tire carrier option:
Were the upper holes needed to mount it, pre-drilled into the upper flange?...or were they added/drilled and then 'touched up' on the assembly line?
What was the distance(s) from the front bed panel to the wheel centerline?

Its great to see old threads do some current good.
If the carrier is factory stock it will be listed as P13 S/M WHEEL CARRIER on the SPID. However many were sold as GM accessories and many aftermarket versions exist.

It was located, by the factory, on the left bedside forward of the wheelhouse. The mounting specifics are in the assembly manual.
Off the top of my head there is a smaller than standard floor bolt hole that locates the carrier it and two other holes are drilled to fit upon bed assembly. If I get a chance I will confirm/expand later. It has two or three different distances SWB, LWB and I believe Longhorn specifc. Really need to dig through my assembly manual. But basically the tire tucks to the wheelhouse.

I moved mine from the rear bed drivers side to the front bed passengers side for weight balance and to get it out of the way when using the bed. This is what the old existing holes look like.

Interesting.....makes me wonder when the holes were added on the assembly line.
you would think before paint?.....or did they include it in all the truck beds from the get go?

I think they mostly just drilled out the rail for the top two mounts at the dealer and then reused the lower bed bolt. My bracket had the matching original paint but was mounted at the rear (which doesn't sound standard). The top holes were not tapped, just drilled. It had very little surface corrosion in the hole, maybe because it was high up and didn't get too wet over the years.

I investigated all that so I could prep it when I moved it forward and to the other side.
Hope that helps.

Not sure why you think yours is a particularly useful reference. Clearly its not the factory location nor hardware. Looks like they only used one bolt on the bottom as well.


The RPO P13 carrier replaced the standard P10 uderbed carrier.

On Fleetsides it was located by a production reference hole in the left bedside floor flange.

The locating hole was opened for a production through bolt and an existing fastener (@ station 72.49 or 84.49) hole used for the other lower corner.

The bottom is secured in two locations with an existing production bed floor bolt hardware stack and an added bolt of the same type.

We know the carrier top was match drilled and through bolted with phillips screws, nuts and washers.

Of interest, spacers (crush sleeves?) were also used on RPO E81 wood floor Fleetsides and two different carriage bolts were used, 10 series and 20-30 series.

I would not pretend to know factory restoration facts. Mine clearly was not factory. I just found it unusual that it had the original paint on the bracket if it was not factory. I guess it could have been painted to match and then mounted by the dealer or the owner.

-
As long as this was bumped to the top I will add pictures of the original NOS hardware I have. The first picture is the individual pieces and the second picture shows all of the pieces assembled. I think the picture above from the assembly manual (post #21) shows the two different nuts depending on whether the spare tire hardware uses the lock or not. The part number for the special nut is 3682846. The box is for the lock.

Good info here. Thanks

Here's a pic of mine

[72 tigger]

Installed one on mine today. I know the wing nut isn’t factory correct, but it looks period correct to me

[B. W.]

Hey Tigger, what size tire is that, I'm trying to determine the largest tire that will fit on a short bed mounted in the same location. Thanks. BTW, I like your wingnut setup better than the factory double nut.
