People never have a problem until they do. Those guys running the CAP upper control arms never had a problem until they split in half behind the ball joint.......
The pics in post #11 are scary. If a motor mount lets go, those lines will be wiped out (possibly the driver and passengers too).
Wonder if anyone has a MC (off brand, after market or whatever) where the lines exit on the engine side, and will fit an a-body. That would be a good option.
