There
is a very small difference, about 3/8". In the picture below, the shiny new one is FE2, and the old dirty one is FE1. I removed the camber cam-bolts and the camber appears to be almost identical with the long arms with the original bolts (non-adjustable).
As for why I couldn't use the arms I have... The rear hole where the pancake bushing goes was bent to an oval, I couldn't even get old bushing out. I'll have to post a pic, but you won't believe I didn't stick in in a vise or beat the hell out of it with a hammer
