Just picked up a 63 wagon. The hatch striker wheel is damaged. Likely unobtainium, but figured I try. I'll try to post up a picture. Thanks in advance. I'm sure there will be more things to figure out as well.

 

1961-63 F-85, Special, and Tempest wagons. Possibly Corvair wagon also. No, I don't have a spare. I have had to disassemble mine and repair it. The failure modes seem to be the spring breaks and the latch pawl wheel gets crudded up and needs a serious cleaning and re-lube. Replacing a broken spring is easy.
