transaxle question????

i currently have a rebuilt 1976 930 transaxle in my street only car. i also have a 76 930 limited slip transaxle needing synchros, etc. on the shelf. would swapping the limited slip out of one into the other be cheaper than a rebuild and if so what is involved with the swap?... also i am in the greenville, sc area and is there a shop nearby for this? thanks for any advice!!

Swapping the diff is best left to a transmission specialist with the appropriate special tools and expertise. My gearbox man says you can swap the LSD with the tranny in the car if you've already taken very accurate measurements of that specific tranny (and the new and old diffs) on the bench, otherwise it really should come out for the work.

If the LSD is a factory ZF, it's really not the best thing to use, JMO.

There's a couple of good recent threads on LSDs in the 911 forum (with posts by Bill V and Paul Guard of Guard Transmissions, aka geary), and many more if you go back a bit further.

The GT LSDs seem to be the best-regarded friction-type LSDs available.

Yeah, swapping diff's is not really a DIY job. It is mentioned in the workshop manual and can be done but rebuilding syncro's seems much more simple than that to me...
