Front wheel speed sensor retrofit ideas?

Ah, that is a bit different than the one I was looking at before. I think I was thinking of Goody's build in my head that used an aftermarket disc brake kit and way different spindles. Racerjoe's setup is pretty much the exact sensor I have though, so nice to know that's one functioning option out there.

I was just out looking at the car and it is going to be interesting. Like you mentioned, pretty sure nothing is going to happen unless I ditch the dust shield or at least trim it out around anything I use. There is pretty much no opening for anything on the stock setup with that all in place. I really like the idea of trying to read off the rotor vanes on the inside, but I'm going to have to actually pull the whole rotor to figure out if that's possible, and that just wasn't something I felt like dealing with today. I wish the rotor just popped off and left a hub under it, but this is an old all one-piece type deal that has the bearings in the rotor assembly and actually has the rotor behind the hub flange instead of sandwiched between the hub and wheel. Something kind of like this I think:

Reading off the back of the studs on that is probably not too bad. Not sure if I could get a sensor turned sideways to read off the vanes though. They are just mighty small diameter compared to brakes today. I think I'm just going to have to bite the bullet and take the rotors off to get a better look though. Guess it wouldn't hurt to repack bearings anyway since I haven't touched them in all the years I've owned the car.

Here's a better view of the back of the rotors:

Might be tough to read the vanes with the sensor I have now. I think it might be too wide to get a good signal. I've got a narrower VR style one, but then I'd need a different signal conditioner, so I'd prefer to use the Hall style one I have now. Looks like I'd have a good shot at reading the lugs though. Guess I'll just have to do the math and see how bad 5 pulses per rev actually is
