i've got these spindles w/the 11.75 adapters on them. but I cant tell if they're gonna be any good. they kinda look like the b spindle in the tech section but the bottom is flat between the b.j. mount holes and the top looks a little different. i got them at the wreckers and they said SATW on them, i thought theyd be from a sat. wagon, but what if they're from a full size. how can I tell the difference, all I have to compare is 72 drum spindles, and they are about 1/2" taller than those. trying to figure out if its worth my while to build this setup up, or just go with a M-II setup, which i also have a few parts for.
