delrin or teflon between leaf springs?

[hpcgmc]

I'm planning on removing 4 of the 9 leaf springs on my 67 GMC, probably every other leaf, in an effort to lower the rear of the truck. I realize that it may ride terrible, or may be ok - but for the price (free!), I'll give it a try.

A buddy told me about an "old hot rod trick" of putting teflon of some type between the leaf springs. This allowed the leafs to move more freely, and stopped alot of squeeking as the rusty steel leafs moved against each other.

I called a shop in Detroit (Detroit Springs, I think) and they told me they sell a Delrin, product, not teflon. I'm familiar with delrin, as I use it to make frame and axle sliders for my motorcycle. I called my local plastics shop/delrin supplier and they have 1/16" delrin sheets, 2'x4' for $40. Anybody every try to use this in between leaf springs to quiet the ride? I'm thinking for $40, if it quiets the squeeking, it will be money well spent. I'm thinking of cutting 2" strips the length of each leaf, sliding them between the leafs and bolting everything together.

Thanks for any input.
