yeah mate..that is the housing and axles..because my diff is narrower than std lx torrie 1395mm to fit big tyres they had to shorten and respline both axles..normally with b/w diffs they only have to shorten 1 axle1-diff conversion(Rodtech Adelaide) $770 - is that including axles or just the housing?
and of course redo stud pattern to your choice..i just kept it torana because i was also reusing std drums

I would say, judging from quotes of other places (that obviously didn't have the jigs already made up) it would be well worth the return freight to use these guys.

couldnt agree more..they have done an excellent job and i can recomend them to anyoneI had mine out of a VQ stato and luckily had a spare banjo hanging about. The whole conversion cost me $680 with shortening (I didn't change stud pattern as I wanted to keep it commodore) the workmanship of this place is second to none. When I told the engineer who had done the diff for his report he said "I don't need to really look at it, Rod is one of my old students and the best there is at this sort of thing"

Even the Selby/K Mac type sway bar bolted up in the same spot.
The wheels ive got have been on there for 20 years +..rears are 14x8 Globeline with 265x60 Goodrich tyres(wide suckers..which ya cant get anymore?)but theres still 20-25mm from the inside of tyre to shocker..but ive also had the guard lips rolled and pumped slightly 5mm..and the rear is lowered 2-2 1/2 "
i'm gunna have to get the exhaust probably altered coz the mufflers are very close to the new 3" tailshaft..but otherwise all good.
i'll try to post up some pics of the wheels when i'm able to
cheers Tim

I also threw in the R31 Skyline option, and was told it was only $200-odd cheaper, despite not needing a re-spline and shorten. WTF?
Anyone know anybody else in Sydney prepared to do it for a similar price that is good?
The other option is to measure it all up and just get my local welder to weld the mounts in the right spot on a R31 diff housing. If I could work out the right pinion angle, mount point etc, that should work, shoudn't it? Or too risky? My tight Scottish ancestry is probably coming out here, but I don't see the value in $1100, especially when I see RodTech's prices.

yes your freight would be huge unless you know a coupla guys who want diffs done and send all together an split the freight price?
the conversion consists of housing shortening, bracket removal and replacement in a jig,axle shortening and respline,change of stud pattern and new bearings and seals fitted
they are great guys to deal with and have been doing this for years..very well respected in Adelaide..Rod is a great bloke an very busy

IMO $500 ~ $750 is prolly ball park for the commodore diff.
Hope that helps.

Maybe I need to go and see them face to face, might get a realistic quote that way.
I'm also thinking of just trying to work out the bracket position myself and get an r31 housing welded up. If it all goes wrong, a new diff housing isn't too expensive.
Is it possible to share accurate mounting points? Or are there too many variables? It's hard building a car when you are a tigh-arse... :-)

Have you tried Richard at Craft or if you want to pay for quality work Terry at Bosinjak engineering?

one of the guys at the workshop had said another test would be to not tighten the diff yoke bolts have them "just" tight so that the coupling/yoke might centre itself?
i had also noticed i used (by accident) different bolt holes in the diff yoke flange ..since the commo yoke has 6 holes but you only use 4
anyway in about a 60 kay drive cruising at 100 kay with a few blaps of 130-140kays there were no vibrations
it was the effing commodore tailshaft diff coupling all along
