Blatman 709 Posted December 2, 2001 Share Posted December 2, 2001 You don't need the angle speedo drive, but it'll help. Shorter prop, yes, and a new (further back) rear mount. Westfield used to make these for narrow body cars (I have one) and is a plate that you fit between the chassis rails in the prop tunnel. Quote Link to post Share on other sites
ACW 199 Posted December 2, 2001 Share Posted December 2, 2001 you will also need a different clutch friction plate. The 5 speed box has a large input shaft with a different spline configuration. What you will need is a friction plate with a 5 speed centre and a Xflow type outer dimension. I think there is a standard car that has these but I got one made by a local clutch manufacturer out of the appropriate cente and outer. Also you probably want some kind of gearbox extension especially if you using one at the moment. Quote Link to post Share on other sites
