Cannot help much really but there are suppliers advertised in the JEC mag for replacements and if you want a rebuild worth talking to http://www.mandcwilkinson.com/sayer-performance-upgrades/gearbox-and-clutch/ who do both rebuilds and T5 swaps or http://www.derek-watson.co.uk/5speedboxes.php or ht...

I have been searching the web but seem to be going round in circles in achieving what I might need. So I have the following questions, bearing in mind wherever I may eventually pu...

Hi Derek I also have a '66 S which has been converted to manual. The correct gearbox for this is the jaguar all synchro and the serial numbers started at JBN, so at a guess KBN is a continuation of that series. You don't say if yours has overdrive.
