Cable, VSS, vs Optical VSS wtf

Ok. help me out. This is driving me nuts.

Have a T5 + VSS for an 89 firebird. This is the magnetic VSS, not the optical one.

Looks like it takes the same gear as the optical one in picture #1 here.

How does the red gear in picture #2 slide over this VSS, since it takes the small gear shown in picture #1?

The Camaro went from cable straight to optical, but the firebird went cable, magnetic, optical. Were ALL the gears the same? Wtf..

Looks like you have cable stuff on the right, VSS stuff on the left.

You just need a VSS gear. The cable gears won't work.

Yeah they don't have them anymore. They say a th350 gear will fit = which it will fit a T5 with cable speedo since its the 1pc plastic gear (the red one in the right pic) but I need the small vss gear only that slides on the shaft.

I ordered a part # from the dealer, 3987920, but not sure what its going to be when it shows up.

Ok that part # didn't work. patc doesnt have 'em, and GM says they are discontinued.

Anyone know where I can get a 19 or 20 tooth gear for my vss ?

well go to a different GM dealer b/c i just got mine fixed 3 months ago. i ordered gears just in case but i did not need them. They exist. the dealer has to ship them in from either motor city or somewhere else. good luck!

You sure? I've got a commercial account with my dealer, and he checked the part #s I had from TGO and they came back as discontinued.

What was the part # you looked up?
