A buddy just brought this over, thought I could use it- a Montague Equipment Co. "All Point Motor Stand" Four-wheel loop-frame stand, very sturdy, machined hubs to rotate instead of tube-in-tube, and four or five different adapters and arms, including one for holding auto rearend housings, all with their own machined hubs, and this one with a single slot about 18" long that he'd been trying to figure out WTF it was for- I started laughing, drug him over to a 390 block on a stand, and showed him the tapped attaching holes in the side of the block, just above the pan rail- did I mention he likes them Chebbie engines LOL- Gotta get some pictures of this critter when I get it cleaned up- gonna be REAL handy, but it was kinda spendy- he wanted $40 for it
