GRRRR!!! got new sterring wheel, already had a boss (Supposed to be for a for sierra, says so on box) but took old wheel off and the shaft is hexagonal and not splined!

 

been on internet to find another boss but none show the middle so don't know if they are the right ones. Are there Two types? I did find one that showed the middle and it was splined so no good.

 

anyone got one for sale 70mm PCD?

I thought all Sierra shafts were hexagonal not splined??

Got a spare Sierra wheel -- fit that -- save money!!

I have a boss with a 17mm hexagon fitting yours for £20 + postage

Wont be able to drive the car with that on bob,! Only just got knee clearance with a 11" wheel.

 

Utuber what pcd is it as it looks like 100mm to me ie for the mountney wheel

I have a spare boss in the garage, it's 70mm PCD to suit the Mountney wheel, it has a hexagonal fit as well. When I get home, i'll post a pic

Had same problem on mine last year,got one for an RS escort off fleabay

looked on ebay but want to see the middle to check and the pics don't show. already paid out for one that's no good so don't want to make same mistake.

 

The old style mountney wheels are 100 pcd my new wheel is 70pcd

PCD ????

Got one from Burton power top kit delivered next day

It means Pitch circle diameter. Unclechief, your boss that they sent you isn't for the American GMC Sierra is it?

I'm sure my mountney one is a hex fit? Not sure about the one that's on at the moment.

You can make an adaptor , i used a piece of ally 10mm thick 6 holes @70mm pcd then another ring of 6 holes @100pcd to convert my mounty mount to match the new stearing wheel

Have just checked the garage, I was confusing myself earlier!!

I have an old Mountney boss with a hexagonal column interface, but it has 100mm pcd for the Mountney wheel.

I also have a 70mm pcd flat faced boss, you are welcome to that to see whether you can make an adaptor as Peter suggests above.

 

Edit: Forgot to add pics
