Kadee's fitted to 4mm (British) stock

[gwfan]

Does anyone have experience of fitting Kadee's to British (buffered) stock? I have a mix of Bachmann, Mainline, Airfix and Lima coaches and wagons and will be using a min. radius of 3 feet.
I have tried using no. 5's but am unsure what to order for the draft gear boxes. Obviously an extended box is required but which one - or would it be preferable to use an extended coupler? I have no local hobby shop and have to order by mail so I don't want to make any mistakes.

Chris,
Rather than hunt through my back collections of UK mags, I found a couple of sites that might be of interest to you:-

Thank you, too. 

I have a 3 coach suburban set I want to fit for push/pull.

Kadee makes a series of couplers with the NEM standard shank.  Check their site. gj
