Driveshaft speed sensor needed

[stony]

I need some sort of aftermarket speed sensor for my car. The EMS im using needs a speed input for stuff like launch control ect ect.

 

Edlebrock and FAST make this thing that goes around the rear-end yoke and uses magnets and would have been perfect BUT it’s for a 9 inch and im using a DANA which is different.

 

I figured I could spend hours looking for something or I could just ask here and probably get an answer in a few days.

 

The fast and edlebrock sensors look identicle. Here is the edlebrock one on summitracing.

Anyways any help would be appreciated

I have seen similar kits for mounting aftermarket cruise control, race car data logging, digital speedomoeters.... however, I always pictured them mounting the magnets to the driveshaft tube, not the yoke. The front (transmision) yoke seems like a pretty good idea, as long as you can center a 1.875" - to - 2" collar ring around it. That might require you to turn the yoke in a lathe for a tight fit.

Here is a slightly dfferent application, with some electronics theory, again sensing at the differential yoke:
