My car is manual steering and 904 . My #3 tube is about 1/2 away from pan. Can't get a finger between them. My engine mount bisquits are about 1.25 inch thick . don't know what the application was, they were given to me. They are about double the thickness of the cheap India mounts that were on there, which I have have been told are typically thinner than stock. I welded plates along the side to make them solid. The aftermarket trans dipstick is very close to the firewall. I had to jack the DS header over to get the torsion bar in. It is very close to the torsion bar and I may tweak it a little more. I have added absolutely no dents to the headers. The car is not yet fully assembled.
