Hi guys, i know this has been discussed befor but i cant find the thread,

but can someone tell me the exact width of a 120y diff from rim mounting surface to rim mounting surface, and the same for a 1200 ute diff?

Cheers!

I don't know how wide the 120Y diff is but I just rolled one(H150) under my coupe(H145) and apart from spring plate and U bolt differences the widths are the same. Just use the 120Y hardware and you shouldn't have any issues.

should be 1242mm from memory

The 77 b210 (U.S. model) that i measured was around 51.75" drum face to drum face or around 1314mm (+/- 5mm for eyeballing it)

as i have custom wheels and a 120y diff at the moment, and am thinking of upping to a 1200 ute diff, im hoping for a precise measure of both, as mines in the car makes it is hard to get an exact measure, if they are different with at all i may just get somthing else shortend, any sugestions, as id like to keep the weight down.

Cheers

I recently have put a ute diff(H165) in my 1000 2-door sedan, well worth the effort!

From memory the difference between the two diffs is about 65mm, i have the measurment some where.

yeah steveo, i know the 1200 is wider than a 1k diff, but i have a 120y diff in at the moment and its wider than the 1k diff, but was wondering if the 1200 is wider again or narrower

Thanks Mate, exactly what i was hoping to hear, the spring spacing is the same as well isnt it?

yep, but the mounts are slightly different

120y has a larger location hole than 1200 diffs as they use the rubber spacer things
