yer welcome!!
that thing has calipers in the rear?! honestly im glad i never had the
pleasure of working on one of these things.
ok heres another thing to look for.
(unless it has a drum brake strictly for the parking brake, this isnt going to help.)
assuming the calipers are ratcheting type, you probably didnt have to ratchet them in, since it probably came fully compressed and loaded with pads. there may be a bolt right in the center line of the piston, on the back side of the caliper case. if so, you need to adjust that (tighten). on a jack stand, the spin the wheel till you fell a very slight drag. once you do stop. if there is a set screw, lock it, and recheck drag. put it on the ground, put a block in front and rear of one tire a foot away, start up the engine and engage parking brake then put it in gear. if it works, (and didnt before, granted this was the culprit all along) you should be good to go.
