As far as switching old centers to new rims the welding part is easy the hard part is taking the centers out of the wheel.
I've looked for almost a year now for those 56-59 wheels and only came up with one set and they were promised to another guy.
If you guys know where there are some please let me know because they don't seem easy to find.
I've made numerous phone calls searching for them and some guys have no idea what I'm taking about and would need a picture to understand which makes the search more difficult.
