Mario,

The cabs are all the same but all the sheet metal forward of the firewall is different.

The 5000 Series is a COE. A 6500 is a long wheelbase (179"), the 6400 is more common. It is a conventional two ton.

'54s also went to the one piece windshield so the inside dash is completely different from '47-53.


'31 Chevy 1 1/2 ton,
'42 GMC 2 1/2 ton 6x4,
'52 GMC 2 1/2 ton 6x6,
'53 GMC 5 ton
