anyone done this also.

No problem,
and yeah the wheels are dodge 20's, $190 US from ebay, about that in shipping and duty and another $400US or so to get the BCD changed.

I got a guy here that builds wheels to make new centres with the right BCD and hub diameter, then he just cut the stock centres out and put the new ones in, it worked a treat and the weld is barely noticeable. He must have done it pretty straight to because the worst wheel only needed 30grams to balance it.
