1987 c60 disc brakes

[bigrigpardo]

well the checks in the mail on the c50 so as long as the shipper doesn't screw me over it should be here in a few weeks. fingers crossed. the truck needs brake work and love the idea of ditching the hydrovac and upgrading. while on craigslist I came across this 1987 c60. looks to be an old uhaul truck probably had frame cut down and the guy mounted the dump but never finished it. question is it has 4 wheel disc hydraulic brakes. hmmm.... what are the chances the front and rear axles would swap into my 70 c50? would the widths be the same. second is are those 22.5 wheels. the tires look very low profile and if they are is that the standard 10x? that the modern alcoas are?
