Yeah I called BS on the van thing as well, though I didn’t look at one. Cass quoted “72 and earlier”. So does the 73-76 sway bar cars need to mount to the rear?
73-76 cars with a sway bar can have the calipers mounted to the front or the rear, although to the front is easier for brake line routing and that's how Cass sets up his 73-76 kit...
