Quaife gearbox modifications

Just posting here in case anyone else buys a new quaiffe gearset and don’t receive the modification manuals. Do not get the gearbox built up unless these have been done or else you will be learning the hard way like I did!! Luckily enough I hadn’t put it back on the car before we realised.

Here's a photo showing where the reverse idler (1st drawing) is located and what it looks like.


Heres a photo of the 1st/2nd synchro ring (2nd drawing)
