MG MGB GT V8 Factory Originals Technical - LT77 gearboxes

especially for Chris - rather than hijack the other thread - do you happen to know the model origin and/ spec of a 20A prefix box ( I happen to have one in my shed) ?
TIA

I've had a chat with the local guru, who tells me that it is impossible to say which car a 20a box came from - apparently the factory (just like Abingdon) put all sorts of boxes in all sorts of vehicles( SD1, TR, Sherpa), so without more info on internal components - gear ratios etc. we can't even start to guess what it was.

Which I suspect is the reason for your question - to find out the ratios etc??
You'll have to do it by rotating the input shaft and counting the output revolutions in each gear to find out...

Chris, thanks for checking, much appreciated. I will dig it out and do the counting, but it might not be until warmer evenings arrive!
