Long story short - the donor car for my mk1 Scirocco had a LOT of work done; TSR engine, K-Star, Autocavan brake bar etc etc. The gearbox was removed due to 5th gear issue and thrown in the boot when I bought the car. Fast forward 7 months and I've just checked the box and it's an ACD. Next to the code is an engraved "TSR" + serial number. Just interested to know if TSR would have done anything more than rebuild it?
Could be just a rebuild, maybe changed the final drive (crown wheel and pinion) ...but it may have an LSD also
Bit of thread revival... I'd think at least it would have had the diff bolted rather than riveted, if it's a full rebuild. You *might* be able to tell if it's got an LSD by draining the oil out and shining a light in the drain hole. Don't think there's even enough room to get a bore scope in there, although I've got one if you want to have a look.
If it has a serial number that would suggest they took the time to document what was done to it. Contact them with the serial number and ask what was done to it
