NOS Truck Trailing Arms? Help please.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

gcburdic · 05-07-2010, 09:27 AM

Hey guys....

A friend of mine has some trailing arms with a GM part #3881314...but is not sure what vehicle they are for....Can someone tell me what year they are for??

I tried to google search the part number and looked at a couple site, but got no results....

Thanks for any help....

According to the GM parts catalog, that part# fits the following:
60-66 10-20 series
67 series 10
67 series 20 (except DoubleDuty)
68-70 series 10-20
71-72 series 10-20

Esentially all 60-72 1/2 ton & 3/4 Ton 2WD thatdon't use leaf springs.

This is what the GM Master Parts Catolog says:

60-64 series 10 (exc. leaf spring 4/WD)
60-70 series 20 (exc. leaf spring 4/WD)
68-70 series 10-20 (exc. leaf spring 4/WD)
71-72 series 10-20 (Conv., DD) (exc. leaf spring 4/WD)

So in otherwords it fits everything from 1960 to 1972 C/10 & C/20 with rear trailing arm suspention. WES

That's great news guys....Thanks for the info....now I gotta see if he'll sell me 2 of them!!!

mclairmo · 05-07-2010, 07:32 PM

Post pics, I've never seen NOS trailing arms.

gcburdic · 05-08-2010, 12:11 AM

Maybe tomorrow...er....this afternoon....gonna pick them up this morning....any idea what they are worth??....

mclairmo · 05-08-2010, 12:36 PM

A lot, used rust free ones sell for over $100 on Ebay. We, in So Cal, cannot even give away used rust free ones, they are all over around here. Nobody wants them.

Agreed...

Can't wait to see some pics Geoff!

gcburdic · 05-08-2010, 10:46 PM

Got a fantastic deal on these....probably keep a set for myself and do some trading for the other set once I figure out what they are worth.....

Got the extra plates on the tops and bottoms too...nice and strong

VA72C10 · 05-08-2010, 10:52 PM

good score...look like the 3/4 ton ones which contradicts the part number info everyone posted....

CE20934 · 05-09-2010, 08:48 AM

Wow! Those are some gorgeous arms.

I'm going to go sit in the corner and turn green for a while.

Do you not sense an opportunity to make a lot of money anywhere in the above statement?

If these are them, you aren't kidding about the deal.

(still envious, but an admiring kind of envious)

gcburdic · 05-09-2010, 10:18 PM

I'm not saying....I'm just saying

Yeah, thought about it but don't have the time and also shipping would be a lot which may discourage some buyers or piss them off. Would also be a b!tch to pack them up properly. We have tons of rust free stuff out here but most are really too big or heavy or inconvenient to ship. I cant believe this dude scored 4 nos arms for $100. What an awesome deal. Good for you. Now go make some money for more parts.

gcburdic · 05-10-2010, 08:19 AM

Who says I paid asking price??

Thanks guys....

Is this also true: "(a) Left and Right sides are identical, which is why only one part number appears in the Parts Catalog. The only difference between left and right assemblies is mounting the parking brake cable clamp (attached on the outside for both left and right sides). (b) Secondly, the same part fits both long wheelbase 127" and short wheelbase 115" models.

Is the Blazer different?

Yes that is true.

For some reason the 2wd K/5 Blazer is not mentioned in any of the parts manuals under the part number for the rear trailing arms. I recall that they are the same.
