Description:

Neil Tyman funded the renowned Quaife to build new robust internals for the fabled Zf S4-12 so it could be raced with even more confidence of reliability and spares etc

Only 20 kits were made for prepaying clients I am told. Some just sold as kits, others fitted. 
This an incredibly rare opportunity to get one of the rarest of rare quaife factory built units that's never been used!

Another onee coming along is doubtful at best. So if the ultimate fSS4 is what you want don't delay on an item that's imo unrepeatable  

Anyone who knows these boxes and cars will know the superb transformation it is from the clunky basic bmc boxes. Fully synchro super strong etc. 

A super opportunity and great investment over a standard ZF S4-12 as spares are readily available unlike the standard box. 

Sold as per the photos with original ZF gear knob again a rare piece in perfect order, gear stick and a couple of rubber gaiter boots if required. 
It is the standard 1" 10 spline input shaft. 
I can also supply a new alloy twin plate race clutch by separate negotiations if interested. 
Assistance in shipping worldwide is possible by arrangement or personal collection.
