PCDs

Anonymous · Post by **Anonymous** » Sat May 21, 05 9:27 am

Yes i know we are brewing up this old "AMCs are NOT Mopars"blah blah again.........But????

My Rambler 68 stationwagon has different PCDs front to back.

3 5/8" front and 4" rears.Why is this? what wheels will fit?

Any help much appreciated.

Has it had a brake conversion or something? Or maybe it's got a Ford back axle or something ...

Actually thats quite interesting,cos it has discs on the front with girling calipers,so it could have Ford hubs fitted.

I measured the PCD from one stud to between the opposite studs(drawing a line between the 2).Was that right?

Oh right.

So if i measure the distance across the centre hole of the wheel,then measure the distance from the centre of a stud hole to the outside of the wheel centre hole,times that bit by 2 then that is my pcd?

So say if the wheel centre hole is 2 1/2" across,then its 1" from the wheel stud hole centre to the outside of the wheel centre hole (twice) then thats the 4 1/2" i should have.

Thats sounds about right then for the backs,but the fronts are about 3 3/4"???

5 stud patterns;
Measure from the center of two holes next to each other.
2.35" = 4.00" Bolt Circle
2.50" = 4.25" Bolt Circle
2.65" = 4.50" Bolt Circle
2.79" = 4.75" Bolt Circle
2.94" = 5.00" Bolt Circle
3.09" = 5.25" Bolt Circle
3.23" = 5.50" Bolt Circle

"What the hell are they" is the next problem!!!

They have Girling Calipers so could be english (granada?).

Or even early Mopar at that cos the stud size is around 4"?

They are definitely smaller.

OK sorry that was wrong.They have Lockheed calipers.

The front studs were 2 3/8" apart (4"/100mm PCD) and the rears were 2 11/16" (4 1/2" /114.3mm).Both are 5 stud.

The backs(drums) are as standard but the front hubs have brackets allowing the fitment of discs onto the hubs replacing the original drums.The rest of the front suspension is as standard fitment.

Going to try granada steels on tomorrow night and also Volkswagon 5 stud on the rear.

Just to continue on from the last few posts,i have now found out that the front hubs are right and left hand thread!!! The rears are both right hand......

I can see some stud replacements coming up!!!

Anyone any ideas what they could be from?

4" PCD,left hand thread on right side,lockheed calipers,vented discs.NO signs of a name anywhere.Could they be early mopar???

4" PCD is early A-Body up to about '73. They had right/left threads. Lots got sheared off from monkey mechanics not havin' a scooby! I'm sure you can still get the reverse thread nuts. Are the calipers on an adaptor plate? Or is the stub one piece?

I know someone who used to own your wagon, I'll be seeing him tomorrow I'll ask if he knows what the fronts are.

Cheers lads.

I'll also take a look at the hubs cos i don't think they had adaptors or plates anywhere.

At least once i find out what they are i can replace the discs. 8)

OK, your callipers are Austin Princess, or at least they were before the guy in Mansfield got it. Some head scratching going on as to what the discs are though. As soon as I find out I'll let you know...

You mean its got race calipers???

Thats good in one way but i am thinking of changing it back to AMC hubs if possible.

many thanks though.
