Ok, i'm putting a T5 from an 85 bird into my 90 RS. The 85 bird used a cable speedo. My RS uses an electronic speedo.
I tried to order an electronic VSS for a 90 RS and the sensor they gave me way too big. It had like a 2" diameter. The cable speed sensor is only 1" in diameter.

My question...did GM change the tailshaft and sensor housing when they changed to the electronic speedo's????????? Or should the 2 be interchangeable???

(sorry for posting in 2 forums)

No they should be the same diameter. Tailshaft et al. is all the same between electronic & cable. For example, right now I have a 91 T-5 (came to me with VSS still installed) in my 83 Z28 with a cable.

Sounds like somebody gave you the VSS for an auto trans.

You can get one out of a trans at the boneyard; AFAIK the sensor is the same regardless of gear or engine or any of that.

Thanks dood,
The first thing i said when i saw the part was "this looks like a VSS for an automatic". The guy at work special ordered a different one, so i'll see it tomorrow.
