i have purchased a lsd from a tt supra snd i have noticed that the prop/drive shaft of the diff end is bigger on the tt than the n/a supra,is it my understanding that the flanges can be swapped from the n/a diff to the tt lsd to match up to the n/a drive shaft....?
my most important issue is the drive shaft couplings on the tt lsd are also bigger,as with the drive shafts bolts,makes sense really... what i wanna know is how to get around the problem of connecting the n/a driveshafts to the tt lsd.
if i purchase the rear tt driveshafts are the splines different on the diff end to the n/a,does anyone know how many splines on a tt driveshaft (diff end) and diameter in mm. so it would be possible to change the ends on the drive shafts to match the tt lsd coupling,therfore i will not have to replace the whole hub assembly,keeping the n/a driveshafts and n/a hub structure as is...?or are they different and i will need to replace the whole hub assembly aswell.If anyone has done this before or has any help please post a comment.
i would be most gratefull.
thanks andy

Sorry I haven't done this swap myself, so I don't have the info to specifically answer the questions you posted. I'd ask though, why not simply upgrade everything to tt (i.e. tt engine, tt tranny, tt diff AND tt driveshaft) all together? That way you know everything will fit perfectly, and it'll all be rated for the same power level. I honestly don't know for a fact that the na driveshaft is weaker, but I'd guess that it may be...
