donnie forrest Posted February 6, 2014 Report Share Posted February 6, 2014 i have a 1973 datsun 620 built 08/73 has the short shaft 4 speed transmission. i have a 75 with long shaft tranny. im looking to put a 5 speed in the 73. i have a crossmember for the long shaft but i dont have a driveline. im looking at buying a 5 speed out of a 1983 280zx . will the driveline out of the 280zx work with my 620? or will i have to shorten my driveline? and will the tranny work out of the 1983 zx ? was told the tranny would work . but i would like to get some more feedback from a few Datsun shade tree Geniuses. Thanks in advance Quote Link to comment

speedgato Posted February 6, 2014 Report Share Posted February 6, 2014 I just installed a 5spd from an 81 zx in my 73 620. Only mod that I had to do was have the front drive shaft portion shortened. After lowering the truck 3 inches, I found that just having a single driveshaft made more sense. That's how she is now. 1 Quote Link to comment

I would love to get rid of the dead carrier bearing in my truck. How is the gear ratio with the 71B trans? And I'm assuming you did this in a short bed truck? donnie: Why not just use the 5spd you have, and have the driveshaft from your '73, built to fit? Seems like a lot less trouble. You can take the driveshaft to a driveshaft shop, and have it lengthen or shortened. Quote Link to comment

No issues at all on the freeway doing around 80 the whole time. 1 Quote Link to comment

Thanks in advance If it's a non turbo 280zx instal the transmission with the front half of the driveshaft and the tranny mount and cross member from the '75. Good to go. Quote Link to comment
