You keep refering to the H190, which is just the bit in the middle,.. the diferential. You want to know about the rear axle assembly.

A number of Nissan vehicles used this diferential in their rear axle assemblies. Some commercial models, some passenger models, & some sports models, all of which had a diferent width to suit the car that they were used under.

According to my literature, the stock track for the rear of a 1200 is 49 inches [it's an original brochure] which my quackalator says is 1244.6 mm, while the Aussie Bluebird is 53.6 inches, or 1360 mm.

It looks like the Bluebird [910] rear axle track is 2.3 inches wider,... per side. Perhaps some Silvia models are narower, but i doubt that you will find a stock width rear axle that comes within a suitable distance. Narrowing a rear axle may ultimately prove to be the final solution.

Ute diff width must be wider. Pretty sure that standard width is 1305mm. Hope so cause my BW diff is getting cut down to 1325mm!

I have seen a bloke getting around in a ute with the 910 assembly jammed under it. He runs FWD offset mags but still uses flares on the rear (has to).

edit: I am running +15 rims, with -35 you should be able to fit them under the guards iff the 910 is only 1360mm.

dodgeman... 2.3 inches either side isnt that much at all. i should have to get the leaf mounts moved and FWD offset wheels but other than that shouldnt it fit?
