Bobby_Lee Posted July 12, 2010 Share Posted July 12, 2010 (edited) History I have an early 260Z that came with an auto trans and R180 3:545 diff. One of the first things I did was swap out the auto for a four speed that I had from a donor car. Fast forward a year or two and decide I want to do the R200 swap. Started reading the various forums about it and went ahead and got the parts I needed and an R200 that I thought was from a 280ZX. I purchased a OBX lsd for it as well. And yes, my gears arrived backward also. So I installed the OBX (after cleaning and insuring the gears were in the proper orientation), new side bearings, seals and gaskets. I start assembling and never thinking I may not have a match between the diff flange and my drive shaft yoke. Hhmmm not even close. So after some further investigating (Thanks again HybridZ forums)I was able to find out that apparently my R200 was from a 300ZX (thanks to a post by howler monkey) So am I correct that I now need a drive shaft yoke from a 300ZX? And that will fit on my 260Z drive shaft? Or do I change out the differential flange? Can I drill the R200 flange to the 260's yoke pattern (I have access to a machine shop)? I'm almost there.......... Thanks ahead of time In the photo....... 260Z flange on the left 300ZX flange on the right Bobby Edited July 12, 2010 by Bobby_Lee Quote Link to comment Share on other sites More sharing options...

I have a R200 out of a Q45, and re drilled it to accommodate the drive shaft yoke pattern. My flanges are just like yours. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted July 12, 2010 Share Posted July 12, 2010 You could also get an early R200 flange from a 280Z. I know the flange is in my diff sticky as part of the list of stuff needed to swap an R200 into an early Z. Quote Link to comment Share on other sites More sharing options...
