MG MGB GT V8 Factory Originals Technical - convert from knock off to 4 lug hubs

Planning a v8 conversion. I have a 1977 MGB with knock off hubs and I am considering changing to 4 lug hubs from another MGB. How is it done, where can I find the information to do it and what year and model MG will work for this?
Thanks,
RIck

The hubs just swap over, it is not difficult. There are differences in the width of the rear axle housings between the wire wheel model and the 4 lug wheel you refer to. The axle housing width is only an issue if you run very wide tyres and they could rub. The offset on the wheel you use has a great deal to do with this.
I am not providing much concrete information here, just saying that it is all perfectly achievable.
At the front dismantle your wheel bearings and install the other hubs. At the rear also remove the hubs and swap the others over.

Good Luck

Not too bad when going from wires to bolt-ons, you can use longer studs and spacers to put the wheels in the centre of the arch. Judging by what has been posted about the differences in axle widths you are talking about 3/4" spacer each side.

Rick,

Could also use a non standard offset to centre rear wheels. The Supersports used ww axle and managed to get 215's to fit in rear arch.

The spacers Paul mentioned give you an opportunity to get the whole thing centered -- as you know, most MGs' rear axles are about 3/8" to the left of center (-- YMMV). I took an MGC rear wire wheel axle and put bolt-on hubs on it ... then I had longer studs pressed into the hubs and had a pair of billet aluminum spacers machined. The RHS one is about 5/8" thick, and the LHS side one is about 1/4" thick. Voila -- perfectly centered wheels (22mm offset Panasports with 195/50/15 tires). Many happy miles and no sign of any problems.

It's my own personal opinion but I would hazard a guess that the axle *is* centred (certainly the axle is centred to its mounting pads), it is the arches that are off. So having different spacers each side would cause crabbing and increased tyre wear.
