just for reference, here are some pics of my B15 tranny swap
B15 w/LSD tranny on the left, B14 no-LSD on the right
Non LSD drivers axle on top, LSD Axle on bottom. the trans spindles are on the right. Note the longer spindle on the LSD axle. Also, the LSD axle is about 2 inches shorter from axle seal to axle seal.
Shift support rod grinding
Instead of having to take the trans out each time to get the fit right, i just disconnected the linkages. this requires you to jack up the engine and loosen the bolt on the motor mount next to the stabilizer rod to get it out *** the bolt prevents the rod from coming out all the way.
anyway, I installed and pulled the linkages 10-12 times before i got them ground down enough. like myprojectB13 says, this is the hardest part. you have to grind a ton to get the two to clear each other
i had to put about a .25" step in thshift support rod bracket
you can see i even ground down the bolt on the shift rod. for reference the two sides of the clevis on the shift rod were the same dimension before grinding,
Id say i ground about 3/16" off the shift rod
these are also located on the transmission swap thread in the tech info forum
For the reverse and neutral sensors, I just clipped the pigtails off my old transmission and soldered them to the connector prongs on the sensors in the B15 transmission. Everything works like a charm!!!
