[Chevelle-List] rear differential bushings

[Drippylimb]

Howdy guys..
  I just installed a set of South Side Machine lift bars on my 65 Malibu. Heres the problem. I need (want) to change the upper control arm bushings to polyurethane.
Most (all) of the companies sell them in sets of eight, but with the lift bars, I only need 4. Would anyone have half a set of bushing laying around that they would like to get rid of ?  My other option is buying a set of aluminum bushings from jegs, but i am not sure how well they hold up to everyday driving. Any Ideas ?

Thanks,
Dan McIntosh
