Safety Question About Replacing Window Lift Motor

I'm doing a number of repairs and renovations on my 1997 GT. So I'll probably be asking a number of questions in a number of threads.

Among the fixes is a replacement motor for the passenger window. I'm roughly familiar with the operation, but different sources provide different sets of instructions, and different warnings. For the time being, I'm using this procedure, which I'm copying-n-pasting from a post in another forum:

1st, remove the 3 bolts that attach the motor to the regulator
2nd, LOOSEN, but do not remove the 3 or 4 gold colored bolts around the motor (11MM bolts).
3rd, wiggle the motor until it comes free from the regulator
4th, hook up all of your wires
5th, line up the 3 bolts attaching the motor to the regulator
6th, tighten up the gold bolts
7th test.

My question is, since I'll basically be fumbling around blind inside the door, is it safe to perform Step 3 without somehow first securing the regulator in place? Is there any chance that the coil spring will suddenly unwind and break my fingers or wrist? If I need to secure the regulator, how do I do this?

I've been stalled on this fix for a couple of days trying to get a definitive answer. The folks at Corral.net have been unhelpful. Thanks in advance.

I'm not old enough to have worked on a 70s car in the 70s, but old enough to have memories of a few injuries incurred over a lifetime of DIYing.

I have, however, read several different sets of instructions on this procedure, and about half of them mention the spring (even instructions purportedly specific to the '94-'04 model year range).

But, cool. I'll take that as a Go. Thanks!
