The collar mounted on the front of the driveshaft will move a lot forward and backward on a ladderbar car, and I wouldn't even try it on a leafspring only car. If mine doesn't work where it is by the front yoke(ladderbars) I will either have to mount two rings together or weld a boss on the tail shaft and either use the parking lugs or mount a collar in there.

How did you guys mount your magnets on your yoke? I have no where to put the collar.  I dont know why your dust shield sticks out so far but if you can push it back you will have plenty of room.. also... if you notice in the couple of pics that the magnets themselves are only a 1/4" in diameter so you dont need to make it much thicker than that EDIT Or do as Monte said.. trash the dust shield and slide the magnet housing to the rear(just clear the case)

Machine the yoke if needed or it can go on the shaft itself. The Cuda was mounted on the driveshaft for years with no issue but it was a 4 link deal.

Stronger? That's a 1350 yoke from Dr Diff.
What's weak about it? My mistake I thought it was a stock one. My Dana has the same issue so I will be ordering one from Summit so I can mount my ring on it

A little late to the game on this but I thought I would add it in case it helps someone. A little garage fab from some scrap aluminum, and a racepak collar, plus a cherry hall effect sensor and bingo, driveshaft RPM sensor. I will use this to log driveshaft speed as well as show MPH on my megasquirt. This is a Moser yoke that I already was using, it has a nice machine 2.125 surface to mount a collar.

This will be short lived, I am putting in my spare center section since I broke two teeth off of the one you see pictured. I just bought a D60 housing to start the journey down that road.
This bracket is a little overkill but its what was laying in the garage, at least it is aluminum lol.

On my Dana,there was no room even without the dust sheild. Bought a Strange yoke and had The Drive Shaft shop "Supershafts" shorten the drive shaft.
HEMI-ITIS has no cure.

Being my trans is out, I've been eyeballing things and am ordering a smaller ring to mount on my output shaft of my 727. I'll just drill and tap the tailshaft and use a adhesive crank shaft sensor spacer. Will be cheaper and easier for me. No room on a D60 for one. I'd have to purchase a new yoke (strange U1598 for you D60 guys)
