Hey guys, this is my first post on here..
My dad just bought a GK scorpion with a 302 :)
Really excited about it! Only problem is that it's 5 stud on the rear and 4 stud in the front.

Can anyone help out and tell me what would be the easiest way to convert the front??

I've read on here that trailer Hub might work and maybe an express van..

Any help will be appreciated!

There is a post on the forum somewhere a member put trailer hubs with I think Holden bearings? The trailer hubs come in Ford or Holden pattern with either Holden or Ford bearings. The Sigma's share the same bearings as the Holden I think? Someone else might be able to clarify?
The Sigma stub axle is shorter, so all you need to do (after the hub bearing combo is right) is to get the inside of the hub machined so the outer bearing can sit further in to suit the Sigma stub axle.

It was done to this car http://www.sigma-galant.com/viewtopic.p ... 320#p22320

Further info http://www.sigma-galant.com/viewtopic.p ... 24&p=51160

I just can't find where he states what he did exactly to the front brake set up on it. It was here in my carport one day after a cruise and the front wheels came off, and much was spoken about the mod, but it was too long ago for me to remember the exact details.

This was the cruise, and has pics of the front wheel off too http://www.sigma-galant.com/viewtopic.php?f=80&t=5413

I hope this helps.

Thanks for the great reply man!

Yeah I've seen this post and have spoken to one of the other guys on here and he mentioned to bolt on the starion front assembly.

Now looking for those or might look more into the trailer hub.

Thanks again!

Hi, you can use falcon xa drum brake hubs. They should be better than trailer hubs
