I don't have a two ton, but since nobody has answered you, I'll take a shot. I first checked American Classic and Jim Carter, because those are two vendors that have been very faithful in supporting our site financially. (American Classic has supported us from the beginning, including buying our servers in the past when we couldn't afford to buy them ourselves.)
American Classic has the shifter parts:
ACCELERATOR PEDALS, PADS AND FLOOR PARTS and the parking brake parts
BRAKE CABLES, PARTS (PARKING/EMERGENCY).
Jim Carter has the parking brake boot
Park Brake Related Parts and the floor shifter boot
Miscellaneous Floor Parts.
I then went to LMC, a vendor I have used in the past that seems to have an extensive catalog. I found this:
Page 46.
They list a rubber cover for the shifter and a pad and cover for the parking brake.
I would caution you, however, that none of these vendors distinguish between 1/2 ton and larger trucks, so I would call them and get clarification that these fit your truck before ordering.
I have bought parts from all three of these vendors and have had good experiences with each of them. I have been to American Classic's warehouse and Jim Carter's warehouse and have met the owners. You can trust all three of them to give you good service and handle any problems professionally.
