I need a diff housing

[shaginwagin]

Thanks to Weasil picked up the beddie diff, today in the back of the Viva, yes it did fit in the boot and back seat down almost into the passenger seat  . Didn't realise how heavy they were until I managed to get it out of the car.

Warren  yes have 2 VN disc brake diffs, take the short side tube out, replace it with the long tube out of 2nd diff, Thats the bit for the diff man to fix it in the correct position. The next bit  will be cutting about 1 inch off the axle to make it fit.  then get a new axle made up so that the splines are long enough to sit far enough into the gears so they dont brake. It then brings the diff back to within about 1 and half inches of standard beddy track. Using the VN front discs instead of HQ because they are about a bee's dick different stud pattern. All the above will be minor  problems that can be fixed

Shane  yes I do have the VN fuel tank that will go into the beddy, fuel pump inside fuel tank need that or the car wont go fuel injected.

I believe the hq stud pattern is imperial and Commodore is metric. The difference is very slight, but, it is real and the two are not interchangable. Someone may need to confirm my thinking. R

Commodore...120mm
HQ...120.65mm...
Dont mix them..the studs break..ugly..

Commodores use a 5 on 120 mm (4.724") PCD. Very close to the HQ - WB PCD but not close enough. If you put Commodore wheels on an old Holden (or vice versa), you will break your studs and be overtaken by your own wheel...not a good look.

i have also had personal experience with breaking wheel studs because of this little issue and its not a good feeling.

just warning you.

Agree Ben

Ive had the same thing - but on the bright side Mr SW could use rims suitable for commodores, go to larger diameter rims and have a better selection of tires to choose from.

I'm pretty sure he was going commode on the front as well.

oh sorry i got the impression he was still running his hq wheels.

the funny thing is that although the difference between hq (4.75") and commodore (120mm) is less than 1mm, it will break studs,
they used to make mags with uni-lug

these oval shaped holes could fit say ford (4.5") to drag (5") and anything in between (chev/hq 4.75")

on a side note, does anyone know the PCD of the current falcons?

Should still be 5x114.3

hmm, still 4.5" interesting. Why not change to metric like commodores?

from the above I take it that Julian will have VN front and rear, if thats so then using commadore/accessory wheels to suit would be the better way to go, as I said most likely a better choice of rims and tyres that way.

I also think a lot of other cars have the same stud pattern - BMW,  Volvo  Range rover etc - might find some flash stock wheels cheap.

It is metric. Its 114.3mm

Yes using VN discs front and rear, haven't had a look yet but the calipre bracket should be the same but if not will make new ones.  Probably easier to make some new ones anyway, got the pattern for the calipres easy to make anyway.
