Buying mechanical parts for a 3800 is a a bit more effort
Most online places don’t list 1 ton compatibility even if it’s the correct part they just don’t know so they can’t help you
With exception of those rear brake drums there is a way to get all the standard parts for your 3800, if you are having difficulty finding something just ask the forum
It will be fun, you should def get a 1 ton
