Got the centers cut out and the rings put on today now I just need to get eyes for the j bolts to go through and get tires mounted this was a lot cheaper option than buying a set of factory dual hubs and I couldn't find a set to fit the 3020 anyway everybody had a set for a 4020 but not the smaller ones I thought about robbing the hubs off my 4020 but then I'd have to buy a set of wedges the best price I could was 300$ as far as cutting a (good) 9 bolt rim apart these are rotten from calcium to just not quite bad enough you can stick your finger through like the ones I took the rings off of
