US Car Tool sells these and I'm wondering if anybody has them before or something similar? This winter I'm dropping the k-frame and rear end in order to clean up the underside but need to be able to wheel the thing around. Maybe it's me but $350 for front and rear seems pretty expensive. Might be cheaper to build a set of my own, depending on the cost of wheels. Has anybody built there own or something similar to it? I'm open to any and all ideas, thanks.
