Izzy Posted July 18, 2017 Share Posted July 18, 2017 Hi all. I'm changing auto trans with W58 trans. I have all the parts including NA driveshaft. As I know, the NA driveshaft have different size flange than TT diff have (little bigger than NA). I'm asking what rubber flex-coupler should I use (is any alternative?) or I must get it made? I know that the W58 trans isn't strong but I got it very cheap. And I have standard TT (no mods) and I drive very conservative Later I'll change it for something stronger Thanks for the answer Quote Link to comment Share on other sites More sharing options...

Scooter Posted July 18, 2017 Share Posted July 18, 2017 You can change the flange on the diff for a NA one if you can find one. I don't think you can make a coupler to go from a NA prop to TT flange as the bolt holes won't align? Quote Link to comment Share on other sites More sharing options...
berg Posted July 18, 2017 Share Posted July 18, 2017 You can make it fit, its difficult and fiddly but it can be done and is exactly how i have mine Im currently using the rear half of an n/a prop on my R154 and its currently mated to a a02b auto TT diff, using the TT rubber Quote Link to comment Share on other sites More sharing options...
Izzy Posted July 19, 2017 Author Share Posted July 19, 2017 Ok I'll try to fiddle away your way berg On the other hand I'll try to draw 3D in CAD and allign holes, maybe I can get some local shop to manufacture new coupler Quote Link to comment Share on other sites More sharing options...
