Before finishing off my build the LSD box I have needs an overhaul as a couple of gears were crunching when I had it on my last starlet. Is there anywhere that I can send it off too that anyone would recommend? Has anyone tried this themselves? A few guys at my work (I work with motors/pumps for offshore) said it's a bastard of a job to change syncros etc. I'm in Aberdeenshire but can travel a wee bit to get it done although I'd rather send it off
