Great project. I thought it was supposed to be a POST '85, not pre-, bell housing with "3F" stamped on it, and the appropriate clutch fork? However, that was for converting an FJ62, not an 80, but maybe it's the same? Sorry, not much help:whoops:
From your other post you have a pre-85 clutch fork, the 85 and up clutch fork is shorter. Note also that the fork end differs and you need the corresponding slave. In the pic the longer clutch fork with the open end is from an '81. The other fork is from an '86.
