I assume it would be J13 if it is stock. I have not had it out yet so i dont have enough experience to gauge as is. And actually, more interested in just the stock transmission only as I am going to lose the motor and make this truck an EV. I want a standard transmission with the stock differential. I believe the stock transmission would likely have been F4W63? I think this stock transmission will be geared ok however it may be necessary to change the differential as well in whole or gearing to 4:33? Still researching this. Any recommendations on locating a differential with 4:33 gearing? Thanks Steve BTW, what is the easiest way to upload my photos to an email/post here? (newbie)

Thank you so much! appreciate the expertise and quick response.

Great Job! On your floor plan replacement, did you shape yourself or purchase. i need to replace on my 1968 project. Thanks

Thanks DanielC. A little more info requested re transmissions. Just bought this 1968 520 PU and it has an automatic transmission installed. I posted a question last month and got the response that 520s did not come with an auto transmission option and that someone must have done a replacement retrofit from another Datsun car model. Understanding and accepting that, 3 questions: 1. How can I identify which model the automatic transmission is? Cast case numbers etc? 2. What is the stock manual transmission model # for my 1968 520? 3. What is the best resource for getting a stock manual transmission for my 1968 520? Thanks all.

Looking for the differential ratio for my stock 1968 520 pickup. Thanks

thanks for the quick response. The motor is really small (front to back). I will find out what series it is but I think it is stock. I see a hole in the firewall where the clutch cylinder is missing so maybe a retrofit with the auto trans. Does not really matter though as I am going to make this truck into an EV. So as long as the auto trans turns the differential then I am probably ok. Thanks

Newbie here in so cal, just bought my first datusn truck. gonna do a full restoration. Truck has auto transmission, could not find any info in the original repair manual. Does anyone have a resource for basic info on auto trans. Thanks,
