Pity you didn't come here before buying. Extended studs and spacers are a pain and add another element of concern to your wheels. With an 8" wheel, you'll need to space them for a 4.5" backspace,

These wheels are 17x8 and require no spacers or special studs. The late-model "Bullitt" wheels are an imitation of the original Torque-Thrust wheels, made to fit the offset of the modern Mustang, these are what they are imitating:



Maybe these folks can help you:

the BS is 5.72", so 1" would make it 4.72 BS

Still too much. 1" spacers would make that about a quarter-inch too far in.

So to clarify my confusion I have a 68 that at Mustang week at Myrtle Beach I bought Chrome Mach 1's with 5.72 BS. I need them to be at 4.5bs so a 1.25 adapter/spacer will do the trick and the wheels will still be in my wheel wells?? Thanks I have been confused all day.

I used the Vintage Venom brake kit, but they also sell a kit for putting the wheels off of 99-04 cars on the Vintage mustangs.

Wheel Conversion Kits — Vintage Venom - Vintage Mustang Disc Brake Kits





This is a 17x8, 5.72BS, +30mm offset rim w/1" hubcentric spacer on the front.

Of course, you can get wheels that look exactly like that and don't require adapters.

Just a point of clarification....4.75 bs is the better fit than the 4.5...so if you are buying spacers buy for 4.75.

I did it with

1.25 inch spacers. This was back in 2003.
But I wish i had used the new properly backspaced wheels available today.
What ever you do, weld those studs to the drum!
had mine come loose on the rear tire and almost crashed!
thank god i had just got off the freeway and was only going 20mph
