65-70 FS polygraphite front bushings
If you own one of these, you know there is no polygraphite bushings available for the dark-siders (65-70 FS) front a-arms.
What I know: the lower A-arm has the exact same bushings as the 69 Grand Prix, which is available in Poly. The upper A-arms are different, but only a little, and I think I can ream and shim my way into polygraphite, so I thought I'd try and and post results.
Here's the size breakdown:
Fullsize upper bushings '69 Grand Prix Note
Shell OD: 1.3" 1.3" Perfect fit
Bolt hole ID: .69" .68 Ream .010" to fit(or turn down shaft)
Legth: 1.78" 1.76" .020" washer shim(if it's needed)
I think I can beat the forces of "anti-full-sized pontiacs" and actually get what I want.
Comments anyone? I've ordered the kit, and will post results soon.
