Thanks for the info, I have a ring from Racepak and I would like to not have to take the yoke off the rear to install it.

if your careful you can do the modification to the yoke on the car ,I did it on the car for the same reasons

What did you use to grind? A sharp flat file, Dremel, or a die grinder maybe? I'm thinking I have to pretty precise to keep the collar true.

Believe it or not an electric grinder and a fine touch. all that has to happen is the four square corners need to be rounded out equally and a lot of grind, fit, grind, fit, etc.

Dion, your collar must have been a different width as I couldn't find a way to fit the racepac collar on my yoke without a lot of interference. Mark Williams didn't make a 12 bolt yoke with the clearance machined and woudn't make one. So I had strange machine a chromemoly yoke. Looked cool, and so did the blue print . I made a mount to bolt onto the center section webbing to mount the pickup.
But then, maybe your are just that much more accurate with a grinder than I am .

I have a Mark Williams yoke ( for 1350 u joints) and a 12 bolt and the collar bolted right up. I don't remember the part number, but it was an off the shelf item.

Mike I use a computech datalogger and possibly the collar for the yoke is narrower as it didnt take much grinding to get it to fit. I now have a Mark Williams 1350 yoke and the collar just fit right up no mods neccessary. Also my job includes a lot of power tools and precision contol :)
