Yeah i have, its a t61 aka t04s, t4 style exhaust housing, i'd rebuild it myself, so the companies want to know the serial number to get the correct parts. I'd need a rebuild kit (seals, thrust bearing etc), plus the main shaft, and possibly an exhaust housing, which doesn't leave alot left of the original unit, i might as well get a new, bigger tubby! I've got another wastegate coming, which i'l be doing over the next couple of weeks (work depending), so watch this space!
