[DeTomaso] Two Pantera Questions

[michael frazier]

I have to agree with Goram.  The engine alone may twist but once connected to the trans and thus the ground it
would try to rotate opposite the wheels.  I've seen the rear mounts live long in high horsepower units.  I've seen them break
in stock applications but I attributed that to letting the fittings get loose and everything was shifting when they went.
I've had both with no problems.
