smurfy Posted March 9, 2003 Share Posted March 9, 2003 I have 4 sp. Quaife Rocket straight cut box that is in good condition but in need of a set of synchro rings. I also have a good type 9 and have heard that 2nd hand rings if in good condition can be fitted. Will the type 9 synchros fit the 4 speed box or would I be better buying new and are they available ? Thanks for any advice. Link to comment Share on other sites More sharing options...
Hippy Crippy Posted March 9, 2003 Share Posted March 9, 2003 The type 9 and the rocket box are different gearboxes to start with, therefore, unlikely the parts will interchange. Also, if your gearbox already has quaife internals which are straight cut, I think you'll find the type 9 has helical gears. Best bet phone Quaife for advice as they produce gear kits as well as full gearboxes, so probably do spare parts for your box. Hope this helps.

J.R. Posted March 10, 2003 Share Posted March 10, 2003 Type 9 baulk rings are far weaker (they crack from a very weak section that locates the blocker bars) and also wont fit the 4 speed box. 4 speed synchro rings were available from Ford the last time I bought them, the difficulty is finding a person at the parts counter who knows of the existence of any Ford cars before the Sierra 🙆🏻 Link to comment Share on other sites More sharing options...
smurfy Posted March 10, 2003 Author Share Posted March 10, 2003 Thanks for your help guys. Seems like parts availability is now an issue. I have located some 1st / 2nd gear synchros but the 3rd and 4th are a little more difficult. Any ideas or contacts. Link to comment Share on other sites More sharing options...
peterg Posted March 11, 2003 Share Posted March 11, 2003 You're best off talking to Phil Stewart at Road & Race Transmissions for anything to do with Quaife boxes 01959 525105 Link to comment Share on other sites More sharing options...
