I've got an older Fat Man Fab Mustang ii front end on the Pumpkin with shot bushings. Does anyone have any knowledge on replacement bushing for these. I called Fat Man and there want $60 a set, and wouldn't give me any part numbers to try to find at the local parts house. They are tubular lower control arms, non factory style w/o radius rods. I haven't taken any measurments from them yet. Just seeing if anyone has come across something like this before.
