I have a '65 Ginetta G4 with a BMC rear axle located laterally
by a central a-arm and fore/aft by a trailing arm at either side:
== == == ==
|| \\____// ||
|| \\ // ||
__||__________\\//_________||__
__==___________<>__________==__
The trailing arms have a metal-rubber-metal bushing at either
end; the a-arm has the same bushings in the legs and a spherical
bushing at the point.
First question: does anyone know where I can get replacement
bushings? I believe a similar set-up is used on the back of
Lotus 6's and 7's. I believe the bushings have an ID of 1/2",
and OD of 1 1/8" and a width of 1 3/8" (I'll check to make sure
if anyone knows where I can get something close).
My machine shop will gladly make Delrin or aluminum bushings, but
I'm concerned about the hardness difference. Second and third
questions: am I likely to crack the frame with the harder bushings?
Are the harder bushings going to make the back-end skittish?
Any help is appreciated.
