Can someone clear a few things up for me in reference to rear control arm bushings ( 1972 Vega Wagon).
My GM Parts manual says I need the following control arm bushings for the rear:
3978060 (quantity of 4)
3997973 ( quantity of 2)
3988064 ( quantity of 2)
There is a guy on ebay selling a complete set of 8 bushings (cheap compared to NOS). When I asked him if they are marked as to upper rear, lower etc he said no.... they are all the same size.
So... What's going on? I find it hard to believe that GM would call out 3 different part numbers if the parts were indeed exactly identical to one another.
Are the differences so small that basically 1 size fits all?
I'm looking for GM NOS by the way, no polyurethane please!
Any insight/help/comments appreciated
