My point was (or should have been) that a cross-threaded tap might be worse than a cross-threaded bolt.

Jim,
My statement not directed at your comments but as, just another.

Once I had the trans bolted in, THEN I movd to the motor mounts at the back of the car. Once all the motor mount bolts were tightened down, then I snugged up the forward trans mount plate. Piece of cake!

+1 on that everything a little loose then tighten. regards , ben

And the good news is: when you hopelessly cross thread the mount, you can repair it with a Helicoil. Many, many 911s have at least one of these repairs to this area.

I don't recall that these are a non-standard thread, though. Otherwise Helicoils would be hard to come by. Or replacement bolts, which I have purchased.

You need to repeat the mantra: it came out OK, so it should go in OK, so I will, under no circumstances, apply any real torque to get the bolt started.

Easy to say. Frustrating to put into practice.
