Cobra r wheels not fitting on the rear, nine inch center hub two big? Any Ideas on this, I have heard make the hole bigger on the wheel, I have heard have axles cut down, new axles with flat ends, and 3/16 or 1/4 in spacers.

I did some reading on other forums and some people bore the wheel for this issue, what do some of you think?
I personally would have the axles machined down so in the future if you wanted to change wheels again, you wouldn't have to have the new wheels bored out again. just my .02 though
If he gets the hubs machined down then you run into hub centric issues with the rotor. I believe brakesrus.com makes a lot of them and may make one for this application. The adapter ring will keep the rotor centered on the axle which is how the rim will be centered.

Ok, let me say this another way. If he was to scribe a line on the hub section just on the outside of the rotor and measured (or got the measurement) on the inside of the center (hub hole) for the wheels, he could have just that section turned down. I didn't make that distinction in my other post. Sorry.
But on the other hand, it probably would be a whole lot cheaper and quicker just to get those specific spacer rings and be done with it.
I remember back when.... when I had run some wheels on a 74' Gran Torino that used the shank type lugs with centering washers (if that's what you would call them) and the center holes were larger than the hubs, man that was a ROYAL PIA to get them centered properly.
talked with a guy here in town that owns a machine shop, he does this and new what I was wanting to accomplish. He says people run into this trying to mount factory wheels to other cars or trucks, he told me 20 a wheel. I am going to do this since I got wheels really cheap. Cause if I want to change wheels later, I am going to take Darrens advice and get rear end out of a 98 gt. I am going to go 94/95 front rotors too later.
Makes sense. Good luck
Thanks I will post some pics when I get him to do them.
