Factory Slotted Alum Rims won't fit....?

Ok, been working on getting these factory slotted alum rims ready for a long time, put new tires on them, and now they won't fit on the rear of the car?????

I looked and it appears the hub on the rear drum is approx. 2 3/4" in diameter, where as the center hole in the slotted rim is only 2 3/8" in diameter? I didn't think there was going to be any problem with installing these rims, what's going on? Am I missing something obvious? Do I have to get longer lug bolts? Even if I did, it seems like the alum rim should go over that hub? Help!!!!!!!


Thanks...

I am gonna guess that the rims are early style.

 

the rim does need to go over the hub. you need to have the centers of the rim machined to fit over it or the hub machined to fit into the wheel. you could try grinding the wheel center your self to clear it or take it to a machine shop and they should be able to do it for you.

 

You have the 73 rims, 74 & up the hub size changed (front & back) they may even be 73 Mustang rims.

 

What about axles with a smaller hub?

 

Oh man, I didn't know there was any difference. This "rim project" has gotten way out of hand, I've got sooooo much money into these things already, I can't believe I'm going to have to dump even more money into them....

Thanks for the info. I'm not even sure where to start in finding a machine shop. Do you think I'll need to have the tires dismounted?

 

Almost definetly with any rim work. I thought that the early axles have smaller hubs. That could be an option..

 

Early axles are 1/64" shorter so that’s not enough to worry about

 

lol.. That could be the difference in a deburring.

 

My bad. it's 1/32" difference. 25-9/19" vs 25-35/64" and 29-5/8" vs 29-39/64"

 

This whole ordeal is almost making me sick. Live and learn I guess, I could have gotten brand new rims for the price I have into these already. Maybe I should just sell them and cut my losses. Anybody know what the hole size was for the "second generation" slotted rims...? I'm guessing there is enough material in these if I do decide to have them machined?

 

We've talked about this for years. I learned the hard way, at 4 o"clock at the tire shop 20 years ago.
I tried to find a machine shop that would open mine up for me, and no one would touch them. Southern Ontario was filled with machine shops supplying Detroit, so it's not like anyone didn't have the equipment...

 

Any idea what kind of money we're talking about to have a machine shop open up the centers......?

 

Not sure if any of these guys can do it. I tried to call one and realized he was in California. He took my # and was gonna get back to me. So I changed the search. The second one here seems intresting.

I got my wheels fixed once. They were bent. Costed $135 ea.

 

Gene,

Thanks for the info, I'm going to email them and find out what they have to say. From what their website shows, this should be an easy one for them...
