GM 12 Bolt - Racepak Drive Line Sensor Bracket
 

Is anyone running a Racepak driveline sensor on the GM 12-bolt? Looking for some ideas for the mounting bracket

About 6" long piece of angle aluminum stock with 2 holes through the web of the 12 bolt to mount it. A slight twist put into it with and pair of adjustable wrenches.

I was going to mount on the yoke but would had to remove
And machine a surface for the ring

I just mounted the ring on the Tran yoke and the pickup
Off the tail shaft web. Works good.
I running a metric 200 trans

I built a mount, drilled holes in the webing and mounted there. I still have template I can post tomorrow

Thats how I did mine also.

This is on a Dana but the same idea I applied on my 12 bolt. Just made the aluminum piece a little cleaner. That one we made in a hurry and is the only pic I have. Then a small angle bolted on for the sensor.

I've made a couple, one for my son's and for my own car, both for 12-bolts. Similar to what Rich B. above says, I used a piece of 1/4" thick x 1" wide 90° angle aluminum x about 6" long. Drilled a pair of 1/4" holes through the webs for mounting. Mine are certainly not CNC quality but I think as long as the sensor winds up .050"-.100" from the split collar, you're alright.

I like how clean this looks, Is there a special welding procedure for welding to the cast iron casing?

That I can’t answer, I had Mark Markow do this for me. I will say the collar had to be machined down to fit the yoke.
