Title: HQ stud pattern on diff?

Hi guys,

I am contemplating an LJ diff into early Holden (for the narrow track) but also want to change up to HQ stud pattern.

Would shortened HQ axles work?

Cheers

Ed

Hi Ed.

That would probably too much mucking around to do it that way.

The rear axle bearings are not the same.

It would be easier to just shorten an HQ-HZ housing & axles to the exact the dimension required. It would be cheaper & easier to do the re-spline in the later 23 'fine-spline' style & use the later side gears. Stronger as well.

Dr Terry.

In my EK I have fitted a narrowed VR Commodore diff , gives you disc brakes and a 4 pinion diff centre , I had the bolt pattern changed to HQ by buying 1/2" wheel studs and offset drilling the existing holes as they are only 0.6mm different.
