Thanks

The rear disc nuts are 11/16 AF, and the thread is a fine thread. Seeing as they're Jag bits, they may very well be BSF or something very English rather than United National thread form(American)...

ward engineering would know, and could supply you a set if you needed them.

Well nut sure the outside matters if you changing them, as long as there the same thread.
I'll messure the one on my spare diff tonight.
I work next to a big nut and bolt disp. so no problem getting some. just needed to get some otherstuff today and wanted to kill 2 birds with one stone.

going to try and get some all metal lock nuts are the nylocks can melt if you get the disc's too hot.

The drive shaft flange nuts are 7/16 UNF (on my car) and as stated should be 'all steel' self locking.
I have seen different AF sizes (diff manufacturers) the larger being very difficult to fit due to the socket size.

Nylocks DO melt, my car originally had a sticking caliper and I found small melted plastic pellets embedded in the 25mm flex fuel pipe which are directly in line with the flanges.
