I went looking for one of these a couple of years ago. Like you I wasn't prepared to spend Seventy quid or so on a small length of cable. I believe they are also used in early Land Rovers but I failed to find one for sensible money.
Yes, there is a nice Alfa going the same way on another drive near me. I suppose its often dreams and plans that never get realised when bigger issues get in the way.
This is an interesting thread, apologies to Beagler is it has drifted a bit. I have a K series with Emerald ecu which needs mapping at some point. For those who have been through the process, do the rolling road gents generally require a wide band lambda sensor to be fitted rather that the standard narrow band Bosch type? Can a useful map be produced with the stock sensor.
I am thinking about converting my old narrow track car to wide track. Rather than use the screw on tie rod extensions which come in the Caterham wide track kit, I would rather use proper wide track tie rods if possible. Is it a big deal to open up the steering rack and swap to wider tie rods? I appreciate that this is only an aesthetic change as for road use the handling advantage is questionable.
Intake air should be as cool as possible, I would have thought it could get very warm in that confined box. All the best with the project though. Chris
