I am sort of at a loss for where to go. I really don't want to drop the dough to buy a brand new transmission before exhausting all possible options. No one in my area will work on manual transmissions anymore, unfortunately, so I turned to the internet to look for parts. I finally found what I was looking for on a Japanese parts website (even the Haynes manual for my truck wouldn't tell me specifically what I was looking at).
I have a 1985 720 2x4 truck with a z24 engine. The transmission housing has the number FS5W71B listed on it. The part I'm looking for is "Head, Fork 1st & 2nd" (as well as the pin that goes through the head and into the rod). With this tiny little, seemingly elusive and unfindable part, I would have my dream truck running again.
My question is, I have found some rods with fork heads included listed on ebay that come from a FS5W71C transmission. If I bought those and tried to replace the rod head from the C to the B transmission, would this work? At this point it is starting to seem like the only option other than buying a whole new transmission. I haven't heard back from the JDM websites about part inquiry's. I'm open to advice if you have any other directions to go with this.
