Does anybody have any experience with wheel spacers? I want to put rims and tires from a 05 Grand Prix on my 68 Bird. I know the bolt pattern and back spacing are not right but have found wheel spacer/adapters that could possibly get me where I want to be.

Can't comment on the adapter, but I used 1/4 inch spacers to get my rally's to work with the disk brake kit...all is good there.

You will have to get longer wheel studs. Be sure to get the highest strength available. Look on the Mark Williams website or somewhere similar.

Good point, I forgot about that!

Unless the bolt patterns are the same, longer wheel studs won't be much help. What you probably will need are metric wheel studs if you plan to use the GP's lug nuts. They are probably metric.

I found this website http://adaptitusa.com/index.asp. The spacers also adapt to the different bolt pattern.
