I'm looking to overhaul my front end, and I came across oval or round when looking for a replacement kit... where do I look to see which one I have, and can I tell before I disassemble the front end? (The engine is out, the fenders are off and so is the front... so it's easy to inspect, but I need to know where to look...
On a scale from 1-10 how hard is it to tackle this?
Thanks,
Dennis

rear bushing of the front lower A-arm will be either round or oval. On a 72, it should be oval if it's a malibu, and round if it's an SS.
