The reason I've bought 260z stub axles and matching companion flanges is the higher spline count and I've read they are stronger.Johnymd - Dave J has described exactly how to do the conversion, but you should note :-
a) The 260Z Half Shafts have a different number of splines to the 240Z and will not fit the 280ZX Flanges, so you will need to source a 240Z set;
b) The newly modified setup to the nearside needs to be as thin as possible in order to fit the Tripod type Driveshafts into place ( because of the added width of the R200 Diff ). Even so, you will think that they will not compress enough to do so, but indeed they will - though you may need to remove the studs first and then tap them back into place afterwards to secure the shafts.
You wouldn't happen to have any dimmensions for the finished companion flange?
I have emailed them a couple of time now about shipping to the UK but never had a responce and their ordering system doesn't cope with outside the USA. If some has a set for sale I'd be interested though (I think you need to go R230 and sell be yours!).Go have a look at this conversion package as this is what i am using.
Good info and I am really tempted to stay with the UJ's, just don't want to be wrrying about braking one and be stuck somewhere. I value your opinion so would you say the standard UJ's are as strong as CV's? The other fly in the ointment is my UJ's are old and probably seen better days. Plus the fact I already have the parts to do the conversion, just need to find someone to do the companion flange mod.still running standard 240z shafts with UJs and using avon very soft compound hillclimb slicks.
In 15 years of running the car I have only had 3 UJs break only one of these was on a very aggresive start. The othe 2 went coming out of a corner.
I have seen numurous CV jointed drive shafts break on much lighter cars
In my opinion there is no need to change the shafts. The engineers seemed to know what they were doing when they built the cars back in the 70s
Thanks for all that contributed.
