i made one from the tech tip also. i didnt use wheels but i place it on a dolly to roll it around in the shop. when i put it in back of the truck for transporting i use a ratchet strap to keep it tight up against the front of the bed. it doesnt work as well with the bell housing attached though. if your going to use it on a gmc you need to modify it to accomodate the larger (deeper) oil pans.
