I'm looking for some bolt on dually spacers like would have been used in a dually conversion. The ones I'm looking for bolt on,made of cast iron and 4.5" thick.
I have some for a rear axle , if needed. They are from a company called Arrowcraft and are 3 1/8" thick steel w/ 5/8" studs.


Here you go...

The first pic is decieving, the adapter is only 3 1/8" thick. Also, one had a bad stud that I will be replacing prior to selling to anyone. Shipping will be tough though, they weigh 22 lbs each.
I'm not sure they would work on a GM axle. I know there is something like .400" longer, but can't remember which is longer, GM or Ford. Can't say that I've seen the other ones.....
