Thanks for helping guys.
I race my knackerd old sierra in the super rods down in dover and when the is damp (all the time) i get no traction what so ever out of the corners so i'm gunna try a welded rear diff.
I found a diff from a saff cos and it says it had been welded i didnt even think about it being an lsd . Thats either a waste of time or someones telling tales.
If it dont fit then i'll just get mine welded.
Thanks
