I needed the wheel off, and have misplaced my old diy puller. so here's a little post for content on this simple tool. No need to buy one. Works well with the 64-66 wheel. Unsure what else it'll do, but you could drill the holes accordingly and add different bolts if necessary. 3/16" thick 1 1/2" angle ir...
