A work collegue has recently bought an FJ ute. Against my repeated criticisms he went out a bought a 350 Chev, TH400 and CRS chassis kit plus more. As you all guessed the engine is too big to register in NSW (301ci is the biggest allowed) - I'll help him to solve that problem with a 283 (which can easily be stretched to 327ci). But he needs a diff. A 9" is too big and heavy. Has anyone out there fited anything that is stronger than a banjo that is about the right width? I believe he is fitting Commodore discs to the front, so the stud pattern will probably have to be able to be modified to 120mm PCD. Volvo, Mustang, A9X?

Wouldn't a Vb-VK one be close to the same width as a FJ? Maybe offset the rims?

john,
i know people who have used these early commodore diffs, in fx/fj's
they do fit, but you have to run almost flat rims to get clearence under the gaurds, i found in my situation the shortened VN was better as i could adjust the width to centre the

About six years ago I had a crazy next door neighbour who fitted a 351 Cleveland and top loader into an EH. He used a V8 Commodore diff. I am not sure what model it was but it fitted without narrowing. It was still going well when he sold the car last

The EHs are pretty narrow when you think about it. I have seen a Morris Major (same as austin Lancer) with a EH back axle in. He had a hot motor and kept breaking Austin diffs, not surprising when they are basically the same as Morris Minor diffs!

Thanks Les. Wrong Byron though. What axles did you use? You can't respline Holden axles without re heat treating them.

byron, sorry for the confusion, thought you were someone else.
to answer your question, i am running a shortened VN diff, using one original VN axle and one axle from an early 10 bolt salisbury V8 commodore diff, same splines and you dont have to shorten

Clever. So I'm guessing you turf the VN long axle, swap the short one over to the other side and fit a Commodore 10 bolt axle into the vacant side? No stud pattern or flange size change either. Will investigate. Could you please email me the contact detai

Always a cunning stunt somewhere isn't there. Have to admire lateral thinking.

The easiest way to make a 9" diff fit a HQ-WB is to weld on the old Salisbury tubes, complete with mounts and guess what - VN axles are the right length, and have the right backing plates even. Commodore discs bolt straight on too. Never tought of mi
