What year and model Chrysler is this?

Not entirely correct. So ‘83.5-‘84 Shelby Chargers and ‘84 GLH were 4x100 with vented front discs and 200mm rear drums. ‘84 Daytona TurboZ had 4x100 vented front discs and 220mm rear drums. Starting in ‘85, with all GLH(turbo and non turbo), Shelby Chargers and Turbo Zs, we’re 5x100 vented discs and 220mm drums in the back. The GLH/GLH-T and SCs, including the numbered GLHS models used the same 5x100 front vented discs and rear 220mm drums.

An upgrade for ‘83-‘84 GLH and SCs is to install the 220mm drums off of an ‘84 TurboZ and front calipers and brackets off of the mid ‘80s caravans. The Caravan used a larger piston caliper with significantly larger pads. The front caliper/pad upgrade also works on the ‘85-‘87 Lbody turbo models.
