Hi Tony. I have a Lotus Esprit but I dont have the upgrade kit in it.
You're right about the price of the upgrade kit. It is very pricey.
I have upgraded one of my UN1 boxes for use with a 406 V8.
What I did was to check out what was done with the ugrade conversion and then armed with pictures and facts, trotted off to my local gear cutting/machining company.
They had done similar things before for other boxes so this was no different.
I wound up getting the same thing made for less than half the cost of the advertised upgrade. Also a few other small mods done at the same time - and you can get the clutch spline cut to what ever you want as well. But there is nothing wrong with the Ford one, as Ive gone to that!
