That's certainly good to know and sounds like the direction MrJuanderful should be looking.

Brad, you said you started with an 8 lug bread truck and swapped 5/10 lug stuff. It sure would be easier if MrJuanderful can just start with the 5/10 lug stuff. Just look for the right chassis and skip the axle swapping.

To keep the available 19.5" wheels that are usually 6" or possibly 6.75" wide 8r19.5 tire is as tall as you get. Not really any good taller options even if you had a wider wheel, not that wider would look right either.
9R22.5 tires seem to be just about the right looks and size for the AD Big Bolts. Only trouble is finding the 22.5" wheels with that bolt pattern as they came from 55-59 Chevy 1.5 tons only and many of those trucks had 20" wheels not the 22.5".

If you're set on this project the 5/10 lug independent front P-30 and 55-59 22.5" wheels sound like your best option.

Alternative is stick with the original truck chassis and swap spindles and disc brakes over to the original front axle as laid out in the disc brake conversion thread. Also swap the rear and you'd be still be looking for those 22.5" wheels.

Or same idea as the disc brake swap to old axle and chassis but with the 6 Lug Budd bolt pattern, like this project. https://picasaweb.google.com/118082002072608219229/53GMCDetroitDieselConversion453TAndRoadranger02
An Oshkosh step van would provide rear axle and front brakes.
the advantage there is 6 lug Budd 22.5" wheels are quite easy to find.

An in my opinion lesser idea would be 8 lug P30, expensive aftermarket wheel adapters and 22.5" semi truck wheels, but I think that just looks wrong, and you'd have relatively small brakes compared to the other options.

There's always the option of fixing up the original truck as it was and just driving it, that has worked for countless people for years and years.
