I used mike's repair as a guide when I replaced mine. I took a hitch pin and stuck that in after grinding it down with a Dremel. It took forever, but it wasn't hard to do. Ask Mike if he will email it to you, if not, Ill search for it on my computer, its around here somewhere......
Rough guide...
1) Find a good friend willing to help (at least entertain you) (JAY)
2) Cut Hitch Pin Down to Size (Use a Dremel or a cut-off wheel of sorts)
2.5) Bitch about how annoying it is to do
3) Grind Hitch Pin so that it will fit in a rectangular hole. Make sure that the holes go the length of the pin, not the width. Take some time to figure out how the clockwork spring needs to go in order to hold tension and fit on the pin
3.5) Get a beer, or a soda, or a snack, just take a break, or you will try to dremel your brain out
4) Make a metal spacer so that hitch pin is held tight with cotter pin. This spacer goes between the head of the hitch pin, and the regulator. Use some soft easy to use metal, this is basically supposed to act like a massively oversized washer.
5) Reinstall and tension spring.
When I did this, a fellow member of this forum, came over and helped plan out what to do, he also helped grind the crap out of this pin. Cut it down to a rough size first, then go ahead and grind it square. You want a bit to stick out on both sides. I would send photo's of my fix, but my car is currently about 600 miles away *cries a bit* It's not hard, just alot of time, and planning. Think about what your going to do once you have your battleaxe / regulator out of the car.
