Ok, this is the last dumb question I ask ( I hope). Every article I've read on the R200 swap into a 71 Z say's to get the r200 HALF SHAFTS also.Motorsport Auto tells me that the R180 halfshafts will work fine. Has anybody used the R180 halfshafts on the r200 swap?Will it work?

I used R180 shafts with an R200, worked fine. apparentley the R200 shafts are shorter to compensate for the wider diff, though with the range of movement the R180 shafts have inout wise is enough to work with the R200.

i could be wrong but the R200 shafts i think have finer splines that are less prone to breakage? can someone confirm this?

Is there a way to tell R200 half shafts from R180 halfshafts just by looking at them(with out splined section)?

yes all is true the 200 half shafts have a finer spline but i seriosly doubt you will break the r180 ones and origanal r180 half shaft will not fit an r200 because they way they bolt to the diff is different 240 r180 has a plug in style half shaft just like a p510 r160 while the r200 has a flange where the half shafts are bolted on.....hope that helps

My '73 240 had a 180 in it and I swaped in a R-200 and used the 180 half shafts . They had the flanges , just be sure to keep the correct shafts on the correct side they are different lingth.

This is also a stupid qestion but what cars does the r200 come in? I was just wondering if my 79' 280zx would have the 180 or the 200?

My '72 also has flanges on the half-shafts. Was there a mid year/model change?

Look at the R200 handling issues.

I used to think the halfshafts were different on the R200s. Not so sure anymore after measuring mine.

Also the 200 side input shafts are held in with a circlip, so you can pop them out of the side of the diff with a prybar. Not sure, but I thought it was the 180's that bolted in.

Your 280zx would have the R200

I have an R200 mounted in my 71, I have 280zxt CV shafts waiting to go in, Motorsports adapter plates are in. I know one shaft is tinny bit longer then the other, which one go's on what side?

Thanks,

The driver’s side halfshaft is 3/8” to 7/16" shorter than the passenger side.

After reading ( Just a heads up: http://www.betamotorsports.com/benchracing/index.html ) I'm not so sure either.
