55-59 6-lug front disc brakes and original wheels

[roger55]

I just ordered a 6-lug disc brake kit today from CPP.

They tell me that my original wheels won't clear these brakes.
He said they won't clear unless I have 3 1/2" backspace. I measured my wheels and they have 3 3/4" b/s.

It does look like they would be easy to modify though. I think I could grind of the rivets holding the 2 pieces of the wheel together, slide the outer part out and weld back up. It looks like I could get up to 1/2" more backspace doing that.

What do you think of this idea? I sure want to use my original wheels if at all possible.
