Welp, lo and behold I go under there today to find what looks like an FS5C71A with L series bellhousing! AKA an early 240z EDM 5 speed.

I have decided it might be better for me financially to pick up a junkyard FS5W71B and use the rebuild kit I already have.
Anyone got any ideas on what this transmission might be worth when factoring the tired synchros? I think they are like 100 bucks each now!
Here is a photo of inside the fill plug, you can see the synchros are buzzed off where the dog is supposed to grab it



And here is a photo of what it should look like! This is my fathers freshly rebuilt one for his U20 roadster but he wont give it to me!!
