Franken Z Posted May 22, 2017 Share Posted May 22, 2017 I've got my V8 in my Z and the driveshaft yoke did not fit into the 700R auto transmission.(Obviously) I figure I need to get my driveshaft cut and balanced but I'm not sure if I'm gonna need a new yoke, a new tailhousing for the transmission. Thoughts? Quote Link to comment Share on other sites More sharing options...
Miles Posted May 22, 2017 Share Posted May 22, 2017 (edited) What driveshaft are you using? Answers here: http://www.jagsthatrun.com/Pages/Datsun_Z_V-8.html Edited May 22, 2017 by Miles Quote Link to comment Share on other sites More sharing options...
Franken Z Posted May 23, 2017 Author Share Posted May 23, 2017 I was thinking to just use the stock driveshaft until it breaks. I have the Jags that run book and it isn't very detailed... I'm actually looking at it now. Quote Link to comment Share on other sites More sharing options...

TimZ Posted May 23, 2017 Share Posted May 23, 2017 Assuming you need the driveshaft shortened and not lengthened, you just need a new slip yoke that fits the 700r4, and a matching tube yoke, and to have it mated to your driveshaft, cut to the proper length and balanced. If you are planning on keeping the flange and u-joint at the rear of the shaft, a 1310 series u-joint will be plenty strong. Here's an example: https://www.summitracing.com/parts/sdh-2-3-6081x?seid=srese1&cm_mmc=pla-google-_-shopping-_-srese1-_-dana-spicer-drivetrain-products&gclid=CKasltqBhtQCFd23wAod7NoHHA Obviously if you need to lengthen the driveshaft you are pretty much starting over. The 1310 series u-joints (non greasable) at both ends should still be plenty strong, unless you are making a LOT of torque on slicks...

Miles Posted May 23, 2017 Share Posted May 23, 2017 For the same amount of effort, you could buy a Chevy, Camaro etc driveshaft at a wrecker and have it shortened and balanced with new U joints. The only other component required would be the flange adapter. The flange adapter P/N is available in several HybridZ posts. JTR may still sell the adapter. Note: Measure driveshaft carefully Use a reliable driveshaft shop Pay attention to driveshaft phasing/angles Quote Link to comment Share on other sites More sharing options...
Franken Z Posted May 23, 2017 Author Share Posted May 23, 2017 Thanks everyone!I like Miles idea. I already have a flange so it should be a lot easier if I just use a Chevy driveshaft. Quote Link to comment Share on other sites More sharing options...
