yem73z Posted November 24, 2011 Share Posted November 24, 2011 So Im in the middle of a vq35de swap into my 1973 Datsun 240z and I've got the motor in the engine bay all lined up with the rear differential. Now its time for a custom length drives haft with new u-joints....here's where I ran into a hiccup, I have a 93 300zxtt rear diff (r230) mounted and the companion flange has a six bolt pattern. The donor drive shaft that I have is the 350z carbon reinforced stock driveshaft with a 4 bolt pattern flange that mates to the rear diff. What should I do? I have an extra 350z diff that has the same 4 bolt pattern companion flange that I might be able to take off and put onto the r230 but im not sure if it has the same spline count and diameter. Im getting cheap at this point and dont want to buy another 300zx drive shaft just for the 6 bolt pattern flange. Im new to drive line stuff, so Im not sure if there is such a thing as a 4-6 bolt adapter of some kind. I saw an adapter online but im not sure where to buy one should i go that route. anyhow, any advise would be much appreciated. on to some pics now. I have the 4-6 drive shaft bolt adapter pic too, so someone please tell me where i can buy one so i can start taking measurements already. lol.

fast-datsun Posted January 10, 2014 Share Posted January 10, 2014 Why not just get the correct steel driveshaft made and save all the headache in the end???????? Quote Link to comment Share on other sites More sharing options...
