Tom..yes replacing the synchros as pictured. There are 5. Not sure what I am getting into here. Will have to go real slow and take lots of pictures along the way. First time ever opening up a gearbox like this. Engine is in the machine shop and will take several more weeks so have time to get the gearbox done. Sent the cam off to Isky. Datsun guys here recommended them. Called their tech (Rob) and he seemed very knowledgeable about the A series engines. It will be a very similar grind (260/.425) as to what you got from Delta. He referred to it as a mild street cam.

DD...got this kit from a supplier here in the states that rebuilds them himself. Paid $199 with the synchros. Looks to be quality bearings (made in Japan). You familiar with the brand? I think he sent me an extra main input shaft bearing. There are two of those and two smaller ones, total of 4 and two needle bearings. I can only see two roller bearings with the gear assembly all together. Once I get this opened up, I will post back with questions/comments.
