datzenmike Posted March 26, 2016 Report Share Posted March 26, 2016 Hi droski and welcome to Ratsun. I would ask that you start a want ad in our classifieds section... http://community.ratsun.net/classifieds/category/5-drivetrain/?sort_key=date_added&sort_order=desc This keeps our forums clear for discussion and information sharing. I'll leave this post up for now just for information to help you out. Anyone who can help contact OP by private message or this thread will be closed. This transmission would be an F4W63 with a J series bolt pattern. The only Datsun with this is the 520 and the L521 (one year only) I'm afraid. Internal parts only from the later PL521 and 510 with L16 should fit your old one if you know what's wrong with it. 1 Quote Link to comment

datzenmike Posted March 26, 2016 Report Share Posted March 26, 2016 The F4W63 transmission is made up of just two case parts the tail shaft.... and then there's everything else. If you have a good 520 case you could swap everything else from another L series transmission into it. J series F4W63 Notice the center casting line is about half way between the two engine mounting bolt holes. F4W63 4 speed for J engine 520 truck. L series F4W63 Notice the center casting line is much closer to the left front engine bolt hole below... 1 Quote Link to comment
datsunrides Posted March 27, 2016 Report Share Posted March 27, 2016 Remember also that the early 520 used the non syncro 1st floor shift 4 speed from the 320. Total different beast from the later 4 speeds and difficult to find. Some (if not most) MG transmisson parts will swap. The 320 type trans will have a smooth case and a dipstick on the drivers side. 1 Quote Link to comment
datzenmike Posted March 27, 2016 Report Share Posted March 27, 2016 True. October '65 was the end of the old and the start of the 'new' 4 speed. I took a chance it was the 'newer' one. 1 Quote Link to comment
Droski Posted March 31, 2016 Author Report Share Posted March 31, 2016 Thanks for all the information guys. Definitely learned a lot with this post alone already. I should be able to upload pictures of the tranny so I can identify if it's the older tranny or newer version. 1 Quote Link to comment

datzenmike Posted April 25, 2016 Report Share Posted April 25, 2016 I have some saved pictures of a later J13 4 speed... I think you have it. 1 Quote Link to comment
