Tell me about it, I have a modified TR7 item currently fitted and it has a nasty vibration around 50-60 mph.
I was thinking about buying a new one from Rimmers to make another. If it is no good, does anyone know which donor car would have suitable propshaft flanges to match LT77 box and SD1 diff ?
Take it to a decent prop guy and he will make it up from all new parts, there the same mounting flange as jaguar stuff adn they seem to keep them as a "stock" part they even have the sliding joint assemblies
