1968 Rear Leaf Spring Bushings Help!?

[Tireguy87]

I have a ‘68 K20 that I’m just trying to get back on the road. I cannot for the life of me find a set of leaf spring bushings to fit the wider rear springs. I’ve been on the phone with places like Energy suspension, MOOG, and a handful of random spring shops folks have recommended.

I’m looking for someone who has an actual part number for something that will work. Surely there’s a bushing out there for something else that will fit these trucks.

For those unaware, the 67/68 rear springs were 3.25” at the eyes. When you order a “kit” to fit 67-72 pickups and you have these wider rear springs, none of the kits will work.

Do you have an old fashioned spring shop close by that still makes springs? I'm sure they would be of help to you.

See the receipt Clay posted in his build thread here:

He and I have 67 K20's and just redid the springs.

Ok, I'm looking at it trying to figure out which one is the one you need, and not sure. I do know the RB-117 is what we used in the Shackles.

Maybe it's the RB-98, check the dimensions. That's GM PN 3887751 also.

Here's a snip from the GM Parts Catalog. You can still get 3887751 from the dealers.

This might be what you are looking for:

I’m going to try a set of the rb98. Those dimensions seem to be correct.
