Prefect upgrade

[Royalerp16]

Hi, searching for info and came across this site.

I have a 1961 Prefect 107e and want to install a 1500GT engine I have, does anyone know the best upgrade for the gearbox which is an easy installation or can New ratio sets be acquired for the original box. Thanks

Welcome to OSF, unfortunately I can't add any info on your question. Better to post it in one of the technical forums though
