ukspec-supra Posted July 23, 2017 Share Posted July 23, 2017 Need a w58 prop for an auto to manu. conversion;) Cheers Kenneth Link to comment Share on other sites More sharing options...
Mk4Gaz Posted July 23, 2017 Share Posted July 23, 2017 You need to state what size the companion flange is on your diff mate. If you measure the bolt hole centres of the 3 bolts on the flange, it'll either be 90mm or 100mm Link to comment Share on other sites More sharing options...
ukspec-supra Posted July 23, 2017 Author Share Posted July 23, 2017 Its a ukspec tt if That helps? Thx Link to comment Share on other sites More sharing options...
Mk4Gaz Posted July 24, 2017 Share Posted July 24, 2017 My jspec tt had the bigger companion flange on the diff. The w58 prop won't bolt up to it, as the prop will have 90mm hole centres, whereas my diff had 100mm. To make my manual conversion work, I had a custom prop made. You could change the flange on your diff, to suit a w58 prop, but the diff needs to be stripped down and the crush sleeve replacing, to set it up correctly. But, you won't know until you check what's on your car Link to comment Share on other sites More sharing options...
ukspec-supra Posted July 24, 2017 Author Share Posted July 24, 2017 Isnt IT possible to use only the front part of the prop? Link to comment Share on other sites More sharing options...
Mk4Gaz Posted July 25, 2017 Share Posted July 25, 2017 Nope, as the tt auto and 6sp props are sliding, rather than a bolted flange. Link to comment Share on other sites More sharing options...

Mk4Gaz Posted July 25, 2017 Share Posted July 25, 2017 You're welcome. It's very easy to check what one you have, my money will be on the bigger type, which means you'll either have to change the companion flange on your diff (not easy if you don't know what you're doing), or use the w58 prop you source, and have both props cut, and your original end welded on.

ukspec-supra Posted July 25, 2017 Author Share Posted July 25, 2017 Think i will go for your last option;) Do you remember how much you paid to have one made? Link to comment Share on other sites More sharing options...
Mk4Gaz Posted July 25, 2017 Share Posted July 25, 2017 I took all the necessary measurements, and took both props to a local engineering company - who I happen to be friendly with. The guy charged me £50 to cut both props, sleeve the two parts back together, fully weld it, and check it for balance Link to comment Share on other sites More sharing options...

berg Posted July 25, 2017 Share Posted July 25, 2017 W58 prop can fit the larger diff flange, it just takes some persuading to get the rubber coupling on the prop Plenty of people have done it and is how i run mine as my R154 uses a w58 rear section and is bolted up to an a02b diff which has the larger flange Link to comment Share on other sites More sharing options...

Being honest, I can't see it's possible, but if that's how yours is, then fair enough Link to comment Share on other sites More sharing options...
