This is kind of the same concept as Fearlessfront had done to his.. My version has no welding needed.. I just picked up some rims off of ebay that were off of a gt5000 for 30$.. 10$ shipping.. They are brand new.. I took a set of rear tires that I had laying around and put them on the front rims.. I was unsure if the rims would fit on a regular craftsman.. But they did.. Here is a quick crappy video of me trying to explain it..There are pro's and Con's to each way of doing it.. My way I have grease fittings, No welding. But it costs a little more.
