K20 Suspension question
Hi Folks, I have a 71 K20 pickup that I am installing new front springs. I have seen several exploded diagrams of the front suspension. The diagrams show a spacer between the spring pad and on top of the spring underneath the mounting block. My new springs centering bolt head is to short to use a spacer with. I suppose I could get a longer one. There wasn't a spacer on either side of the spring pack when I removed it. The local spring shop that sold me the springs states that I don't need them. The only thing I can think of is they are used to adjust the ride height or they are shims to set the caster. Any ideas? Thanks, Jack

Re: K20 Suspension question
Caster shim would be my thought. My truck has them

Re: K20 Suspension question
Well, I ordered them. I will see what shows up. If they are shims, I wonder what the factory shim size was? I can't find it any where. I guess I will have to put it on the alignment rack and se what I have for caster and go from there. Nice looking vette by the way. I had a 66 convertible also Nasa Blue. I did a frame off on it up in Vermont back in the late 80's. Unfortunately I let it go. I wish now I still owned it. It was a beautiful car. A guy from the Carolina's bought it for His Grand Daughters graduation. I hope She could appreciate all the blood sweat and tears that went into that car. Which engine do you have in that?

Re: K20 Suspension question
I've never known a K/20, or K/10, to come from factory with a spacer or a shim. I have never had to add a shim. Chances are real good your's won't need them either. Got any diagram pictures to show what you think is a spacer? Could it be the nylon anti-squeek pad, about as thick as a piece of paper? They are usually shot and I just toss them. I have noticed no ill effect from them being gone. I figure if they were needed the spring companies would supply them.

Re: K20 Suspension question
I'm sure it is a castor shim. I haven't received it yet. The truck went down the road pretty straight before I took it apart. I won't know if I need to adjust the caster until it's done and I can get it on an alignment rack. That will be a while. But I will post what I find. Thanks for the input Guys, Cheers

Re: K20 Suspension question
I have never had a shim in any of my trucks. I have thrown away the nylon anti-squeak pads that Tim mentioned......

Re: K20 Suspension question
I'm curious: are those anti-squeak pads available and is it really important to use brand new U-bolts whenever the old u-bolts are loosened or removed?

Re: K20 Suspension question
Well my shim's showed up. They are not caster shims but four, what I guess are, anti squeak pads. Don't waste your money.
