[DeTomaso] Adjustable Rear upper a-arms

Tue May 11 13:15:01 EDT 2010

If we do align the toe setting and all the shimming of the lower A-arm,
then loosen the upper A-arm at its chassis mounting and pull it out,
then hold it back against the mounting ears to see if it easy slip in place.
It might do so, but it might even be 1/4" off by the length of the car.
If solid bushing is used this is not good.
