I have fairly close by a vh and vs Commodore being wrecked in a dinky town. I could grab any hard to get parts for myself or possibly for anyone modifying their fc or fe. Only if u can't get stuff from a wrecker in a city yourself though cos I would need to pull it that's all.
Are the rear or front discs (if it has them) interchangeable with the hq?
No
So, was it after hq that all the commodores changed pattern. Is it true that they all used same bearings. Sorry for my ignorance on the 79 to 84 commodores.
HQ imperial stud pattern and no centre bore location incorrect offset for commodore .
Commodore metric stud pattern smaller centre bore diameter load is taken by the studs alone and will break in time .
Yep
