Nathanj1142 Posted January 14, 2021 Share Posted January 14, 2021 (edited) Hey guys just got myself a 46 m3 box for my na-t build (thanks to AC93 for convincing me to not run the w58 lol) Am I right in saying I need to get a hold of the front section of a m3 prop shaft to give to a shop to get one made up? (Already have the rear supra one obvs)? Should I tack up my own Frankenstein prop using both ends to get the measurements right or just measure and send to the shop? Should I get a single piece prop or go for 2 halves with a bearing in the middle per OEM? Also looking for recommendations in Yorkshire for the work! Cheers.

rider Posted January 14, 2021 Share Posted January 14, 2021 (edited) A prop shaft is a pretty key piece to the smooth running of a car and can flip a car if it all goes wrong. So, personally, I'd avoid any Frankenstein offering. Not a million miles from Yorkshire in Salford are these guys who may be worth a call. The options on car and sports car props is limited as most UK manufacturers deal in plant, truck and marine applications. http://www.northwestpropshafts.com/car-and-motorsport Edited January 14, 2021 by rider (see edit history) 1 Quote Link to comment Share on other sites More sharing options...

Thanks for the recommendation! Quote Link to comment Share on other sites More sharing options...
AC93 Posted January 14, 2021 Share Posted January 14, 2021 I think it cost be £250 to get the prop made up, worth doing properly! 1 Quote Link to comment Share on other sites More sharing options...
Noz Posted January 14, 2021 Share Posted January 14, 2021 Would the shop prefer to take their own measurements? Quote Link to comment Share on other sites More sharing options...

I think and fabricator would rather the onus be on you to get the measurements correct. If you use a broom handle and cut to size then that should give you an accurate shaft and coupler length. Then you would just need to add on the spline diameter, teeth pitch number and groove length to sleeve into the axle shaft. Lastly, what material you want used for the shaft and whether one piece of knuckled. Lots of things to work out and get right there. Another reason a fabricator will likely want a job spec rather than a simple can you knock this up for me. Quote Link to comment Share on other sites More sharing options...

Best get on CAD then As I understand i'd be giving them the rear half of a supra one and the front half of a m3 one and they'd cut the flanges off and weld onto a custom length bar?
