HELP ! - Window regulator question

I got my new window regulator yesterday. I just took out the old regulator, and unbolted the motor. I noticed that on the new regulator there are no threaded "inserts" for the motor mounting bolts. Please see pic. Where can I get some ? Or should I have gotten them with the new regulator ? Thanks.

I had to tap the three locations where the window motor mounts with a 6mm tap. Got three 6mm x 1 1/4 bolts and nylock nuts. Motor cinched down and engaged with the "gear" plate.

One thing, though : there is no hole in the base plate and gear plate to lock the gear so that the spring doesn't unwind when the motor is unbolted. The Haynes manual was apparently written back when the regulators had this feature. Luckily, I was ready for the kinda violent separation of parts.

Last question: If there is a paper Ford Mustang manual, is it as vague as the Hayes manual ?
