Driveshaft collar issues.

I'm going to monitor drive shaft RPM using the MSD Grid. Trouble is I don't appear to have any room to fit an 8 magnet collar on the pinion. I'm running a Dana 60 and there appears to be a metal dust plate there, and anyway, it's way to thin @ .200".
Has any used the slip yoke instead? I know it's gonna move but how far?
TIA

.200" is almost 1/4" How is that too thin?

Have you seen the thread about using the park ring in the transmission as a wheel? Absolutely fabulous idea from “dizuster”.
Much easier to run wiring to, and a higher tooth count for low speed accuracy.

Strange has special yoke and collar. did my S60.

I made one. Not for dana, but it fits, without that dust plate.
Next time I would put it in transmission.
Park gear is perfect for that and cheap to do, sensor costs almost nothing.

4 MAGNET COLLAR STRANGE U1617-4 BEST OPTION

Part numbers for the Strange parts.

I went with the Strange pinion yoke which is designed for the collar. You can always fab your own solution but since I was starting from scratch I just purchased the complete solution.

I also had to change the yoke.

if you guys want go to motion race works they have 16 point collar wich works with the strange rear end yoke they used my d-60 yoke for design and i have one from them. these guys make odd ball parts for race cars they are sponcers of JASON DIGBY'S NASTY DART. check out the website or send them a message these guys are making some really cool parts to make things easier for the racer.MOTION RACE WORKS.COM

Well I checked today to see how far the slip yoke would come out with the suspension at full droop. It barely moves, .040" max. Car has a lotta rise on it from launch but it looks like it won't make a difference. I'm guessing that it moves inwards more if the car were to go over bumps. Of course this now presents another problem, who makes a 1 11/16" 8 magnet collar ?
