yes you can.
weld up old holes and re drill separate new ones.
but the mags must have the wall thickness to do it.
- some cheviot hotwires cannot be re-drilled.

"multifit" is ok for a street car
elongated holes

WANTED:
-2 14 x 9.25 CSA style Centrelines.
-2 x 15 x 8 Dragway centrelines

On a related note, I pulled a 9" out of a Torana recently. It had an original set of Ford 9" axles in it with 4.5" PCD. These have bigger neck wheel studs (the bit with the serrated edge that grib the axle). Some smart cookie had come up with the idea that by using specially machined studs that had the Ford neck on them but the GMH sized thread, that if the thread was machined offset relative to the centreline of the stud by exactly 1/8" you could do something very cool. By placing the stud with the centreline of the thread on the "top" of every hole (ie furthest from the centre of the axles flange) you got 4.75" PCD (ie HQ stud pattern). By turning all studs 180 degrees you got 4.25" PCD (FE-UC).

So point is if you could find who made these studs, buy some and drill GMH axles out to the same size stud hole as a Ford then you could turn GMH axles into Ford stud pattern and leave the wheels alone, and drill some drums to suit of course. To go back to the GMH pattern just replace the offset studs with standard Ford ones, use Ford wheel nuts and open the original GMH drum holes up a fraction to suit the bigger Ford studs.

Vintageholden, an engineering shop can, you cant! Haha. Basically, if theres enough meat there and someone that knows what theyre doing, it can be done. Depends on the wheels and how it would handle the extra holes. Multi-fit wheels seem to do ok. Or you get it welded up and re-drilled.

What Byron says is good advice, Ive actually done this with stainless steel pipe flanges when the job required an imperial flange to mate up to a metric one. The difference was about 2.5mm from memory, which may not seem alot, and it would have been a simple thing to just use smaller diameter bolts to join the flanges, or drill the smaller PCD flange out larger. Instead the client wanted it mate up with no short cuts, or extra holes drilled, so the only thing I could think of doing was to make eccentric bolts in the lathe with a four jaw chuck and using over-size bolts and machining them down and cutting new threads on them. Pharmacuetical companies are very fussy.

Peter is right.Just get stuff that fits!These are critical parts of a car,not like fitting a stereo!..Do it right or you will eventually pay for it.

A mates HR wagon back wheel came off at 80kmph (only had 3 wheel nuts) flattened from the top of wheelarch to the bumper.Made a mess of the mag too.

IMHO the important thing is to have the hub the matching size, as this takes most of the weight, the wheel nuts just keep it there...

multifit is 10 holes per rim, i.e 4.5 and 4.75

multi-lug is 5 holes per rim, with an oval hole that takes 4.5 and 4.75 .

If you have tapered nuts, then the load is not on the centre spigot of the axle or hub, the static weight load and dynamic loads including rotational shear and lateral loads are taken entirely on the studs. If you have straight edged nuts with a shoulder that only hold the wheel onto the hub, then a hub centre spigot is required to take the weight load.
