Does anybody know the thread size of the 2 bolts for the rear diff mount onto the diff cover. Thanks.

M 10 on mine.

M12
I must learn to read the hole question
It is 10mm for the rear cover not 12 as I put first
The two bolts are 12mm holding the dif to the chassis

Thanks for the replys guys. Much appreciated. I have already tried M10 and although it starts and screws in about one turn it starts to bind up and is at a slight angle. It's not bottoming out and the threads are clean and undamaged. I don't want to force it just in case I crack the cover.

Im thinking it may be an imperial thread? 3/8 UNC or UNF. I've ordered a couple of these to give them a go. Will let you know how I get on.

What pitch have you tried? There are at least 3 different pitches for 10 mm threads.

Defo 10mm
