Can I change from 17.5" wheels/rims to 16"?

[mattyj858]

Hope some can clarify, I am loosing it on the best solution to the 17.5 dilemma
Read the entire thread but got confused on chassis and year difference


I have a 73 Brave D20 which I believe is a 300 chassis ( according to brochure). This should mean I have a single piston caliper. Sounds like the swap to 16" is do able, right?


If so what Dually wheels should I be looking for, Dodge and what are the right years? I know weight is an issue so any info on the right wheels is appreciated. I will have to used due to to $$$.
