Dually axle question!

So, contact a couple places that have newer ford rear axle assemblies for my conversion of my 65. But, they ask if it is a chassis dually assembly or not. Maybe someone can elaborate a little for me. Thanks

ALL 500 and larger series trucks (all had DRW, some had tandem axles) were only sold as a Cab & Chassis.

There was no "back of cab" equipment available from Ford, so whatever bodies these trucks have, were installed by aftermarket body makers.

I just noticed you said for your conversion, are you swapping from singles to duals? if so you need to measure for tire clearance to frame.

So your looking for a F350 dually axle from a cab and chassis not from a F350 dually pickup. That is probably what they wanted to know.

Beginning in 1973, there are two different widths between the inner frame rails behind the cab. 1961/72 F350's are 33 1/2."

1973 thru 1997 F350's could be 33 1/2" or 37 1/2."

Yeah, I am not to worried on the extra 4"s cause I will not have a bed on it for sometime. I have to get a axle first reman it back to almost new. Then draft up a design of what I am want for a bed lay out.

Wouldn't spoil my day to much. Would push my build to a different route. I am not really going by the book on this one. Not going for a restro on this it is more going to be a usual build.
