Title: Front & rear wheel stud patterns are different
Post by: tradsound on February 07, 2012, 05:44:02 PM

I bought my 78 SWB a while back with front holden disc brakes & a borg warner diff already moded.
My issue is i have a holden 5 stud pattern on my front wheels & a ford 5 stud pattern on my rear wheels.
Does anyone have any suggestions on how i could resolve this issue (within economic reason) so i have the same stud pattern all round & only have to carry one spare tyre? My presence is to stick with ford ones as the mags i like/use are a ford pattern & easy to come by.
Any advice would be much appreciated.

Cheers
Joe

are you allowed slotted mags there? ford and holden (hq-hz) are only half a hole out from each other.

Other option is to redrill front or back disc/axle

Im with Busy...cheapest option..i reckon ..getting back drum redrilled to hq...

you have a good running gear set up..so no need to change diffs...

I believe you can buy the HQ discs with ford stud patterns, that would be easier than redrilling the diff.

Some machining of the discs may be required as per the normal disc conversion, to allow for the bedford outer bearing though.

Hq and ford discs are the same product, just different holes

have you thought of either slotting your spare or re drilling inbetween the holes on your spare i would think it would be the cheapest way. i had an intercepter wheel like this once. worked well.

must try it on a nice day
would be nice if they are
i would think they had an hq - hz parts car
350 turbo 400 and ten bolt diff .. tail lights of a wagon or ute
and the steering column as well
did the hq-hz come out with that combo ?

I concur. I have HQ on the front and Jag on the rear and they are indeed the same with a different size stud. To my knowledge also HQ and Chev are the same.

BMW 5 stud fit too.... but the PCD is different..slightly larger.. so...wheels sit on studs ...

NOTE..... if one redrilles the beddy axle to a HQ pattern, one also has to mill the back of the axle so the studs sit in square at the back..... had to do that to both the axles i scored off ben a few weeks ago, pain in butt, but a necesary one, i used a grinding disc (carefully) to get it down roughly  then milled the last bit to a flat surface
Title: Re: Front & rear wheel stud patterns are different
Post by: ben on May 19, 2012, 07:15:35 AM
whats wrong with using a grinding disc for all of it skip?
Title: Re: Front & rear wheel stud patterns are different
Post by: SkippyThBushKangeroo on May 19, 2012, 11:58:44 AM
less chance of overgrinding, more chance of a nice small flat, level surface for stud facure to butt upto.... guess its the finish ones happy with in the end( not all of us have a masters degree in butchery ben lol )  ;)
 ;D  ;D  will pm you later today ,decided to go with your suggestion of headlight surrounds if you have any knockin around the block ...cheers

small question...   

can i drill the bedford rims to match the hq holden? 
by that i mean...  is it allowed? 
i see rims all the time with 10 holes in them, so cant see any reason i couldnt get a machine shop to drill holden holes in the meat of the rim in between the original holes.

do 3 of them. the fronts and the spare.

Title: Re: Front & rear wheel stud patterns are different
Post by: restoreid on May 31, 2012, 10:52:37 AM
NO The centre hole is too big for the spiggot on the axel anyway
Title: Re: Front & rear wheel stud patterns are different

yep skippy,s right there,
our green n white poptop van has rear axles and rear drums that have been welded up n redrilled to suit Holden HQ studpattern. just done prir to us buying it. by a diff and axle rebuilding shop.
and the spair set of axles that came with the van are welded up and redrilled to suit Holden HQ , the rear have been machined to let the studs press in square to the machined surface, new studs have been fitted, they even had new rear bearings pressed on as well, were packed with greese and sprayed in fishoil to preserve,
god knows how much the prev owner spent just on those 2 axles,  must have been close to $1000 or over...

so i recon get them done right, and you shouldnt have any dramas,
do them bodgey and who knows what disasters will arise.

 weekend is out as have a van club meet
 and the swap meet at trentham on sunday

moved the jumbo today and jacked it up
removed the rear wheel and tryed a spare bedy rim
it fitted  ???  had a better look and think its a 10 bolt center with bedford tubes and axles
have uploaded pic to gallery as for filling and redilling the front to keep my bedford wheels
the hq disk center is to small for bedy stud patten ...can we in nz use a spacer to get bedy rims to fit ?

You can as long as the spacer/adapter is no more than 25mm and it has to have a centre ring for the mag wheel
don't buy the flat ones on tm

Hey I don't know if this thread is still running but all I would do is phone up Rocket in Sydney and order 1 multi fit rim made by Wheel Vintiques. I have holden stud patern on the front of my rod and ford on the rear. All rims are muli fit. Easy Peezy
