Will this wheel fit a W500 (RM400?) chassis?

[Childeric]

I have a 77 Champion that I went to put new tires on only to find that some of my wheels had seen better days, so looking for some nice round ones without spending what I paid for the coach. They are the 19.5 5 lug x 8 style, I found these, I was wondering if they'd work... on the front? I'm trying to get more info from the guy but all I know so far is it's on a Chevy chassis so these should be P30 wheels then correct? I did a search and really couldn't even come up with a definitive answer if P30 wheels will fit a Travco/Dodge chassis... though I suspect for whatever reason... not Thanks for any infoooo.

Seems those are probably 19.5 x 6" and I need 8", yes? thanks

just make sure they do not rub the inside,,,the outside is easy to see but,,,,really bad things can happen if they rub in the back where you cant see....just a THOUGHT...

Found a complete set of real clean and correct wheels on a dodge coach/chassis which was sitting in a field, dey mine now. Has all brand new brake parts too which I have my name on, lucky score.
