More confidence to overtake and bot screaming quite so loudly ( still noisy but thats a landy).
Far more comfy cruising.
I bought an old mot failure for a few hundred quid, conversion kit and clutch comes to about £250.
If you have the time, strip the disco down. Offer parts online. Gearbox ( separate to transfer) and transfer will make money. As will interior, wheels, etc. theres a few threads that explain it well. Langers did a great one
