I'm slowly rebuilding my '79 F150 SWB 4x4. Every part is being disassembled, cleaned, coated, and reassembled. So far, I've had good luck finding parts that are too worn out or impossible to "restore". I may have met my match today. The shifter assembly for my NP-203 has a rubber seal that is dry-rotted and torn is several places. I can't find this part anywhere. I'm not referring to boot inside the cab. I'm talking about the rubber seal/boot that is part of the shift mechanism mounted to the side of the transmission. Does anyone have an idea if I can find a replacement part?

 

not sure about a 203 ,but here is Novacks 205,hope that helps

 

This is my NP-203 shift mechanism. I've also included the rubber seal. The rubber seal is what I'm needing to replace.
