Heres pix of what I did for this. I used 4 10" diameter Bassick heavy duty swivel castors off a machine frame my work was scrapping. These have zerks for greasing the wheels and the swivels. The rear 2 castors are attached to tubing, thats welded to a pair of old rear leaf spring front perches. On the rear castors I welded up brackets with 1/2" diameter solid steel pins that drop down locking them in the straight position, but can be removed to allow the rear swivels to turn so I can spin it around in the garage with all 4 castors swiveling. These swivel locks cannot be seen in the pic, because i added them later. i can take a current pic if anybody is interested in seeing this.
When I decided to get the body up on its side I used a combination of leftover steel tubing from other projects, and some old trampoline tubing I had behind my shop to make a pair of ends that fit into the mounts attached to both the front and rear bumper supports, then i rolled her over on her side to tackle the underside. I believe I have about $44 in the whole setup. The rotisserie ends can be used for other cars too, you just have to make up the pieces to bolt to both ends of the car for these rotisserie ends to fit into.
I was gonna use a metal poly pipe reel to make the rotisserie ends, but could never find one. I think this turned out better though. The last pic I started putting in my home made torque boxes. i still have to fit and install the passenger side front and rear ones, also have a Dillinger lower rad support bar I need to weld in. These torque boxes are 1/8" thick steel plate, along with the 2"X 3" X 1/8" subframe connectors I installed while the car was level before I flipped it on its side. i am slowly getting closer and closer to being able to primer and paint the underside.
