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

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.

Mark Williams sells a yoke but it's about 7/16" longer with the flange for the collar.

A mig welder or for that matter a stick welder. A housing welds easy. I have a yoke from strange the only negative it is longer so the driveshaft needs to be shorter.

Mine is done with the sensor on the front driveshaft yoke and a bracket off the driveshaft loop.
