Where to find help when you want to change major units on your CF - engine, transmission, brakes etc. - or upgrade earlier models to later specifications.

Hi all,
Can anyone tell me if there is a 5 speed conversion / overdrive for a 1985 CF2 2.0 CIH straight Opel engined swb van?
It pulls really well smooth and very powerful but I feel it needs another gear to cruise nicely.

ZF 5-speed with 0.8:1 5th complete with clutch housing as fitted as an option for earlier CF2 models, standard for later CF2 models.

NOT the ZF transmission from earlier models with Vauxhall OHC engine (the input shaft is too short for the Opel engine) or diesel engine version with 1:1 5th.

Requires other bits to make it work: propellor shaft for flanged front end, rear mounting to chassis brackets for cab floor clearance, speedo cable, gear shift lever etc.

Laycock overdrive used for earlier CFs is for the Vauxhall transmission only.
