I have the ZF from a Pantera in the 40 I bought just like yours Frank.If I had build it myself I would turn transmission because you can mount your engine lower in the chassis.This is a change which is high on my modification list.So if you can ,change it now and, mount the transmission like it was ment to be in a 40.Good luck /ubbthreads/images/graemlins/beerchug.gif
