Yes, good luck with the wheels. If you actually have 2 piece split rims and not the 3 piece rims it could be a problem finding a place that will work on them. My 52 6400 has the 3 piece rims, uses 7.50x20 on the front and 8.25x20 on the back. When I got the new front tires mounted I was told that the Cenex I went to won't touch actual split rims. According to my shop manual the 3 piece were standard and the "2 piece" were optional. If you work on them yourself be REAL careful. I have read the split rims can be ok if they are in good shape and are handled right but can be dangerous if they are rusted or damaged. Good luck with your project.
