what cabs can be used

[cdt4307]

Hi the cab I have is in pretty rough shape i was wondering what cabs can be interchanged year wise and size wise ie c10 - c?? thanks in advance any input will be extremly helpful.

c/10-c 80 will work. 60-61 will be called viking or spartan, and have the # series on the fender (60)or grille(61)
the lcf cab (snub nose c/50-80) will not work
there are some minor fitment issues-
front frame location holes are either inboard or outboard depending on the truck- a simple fix by drilling a hole .
c 50-c80 have different lower inner fender mounts, 60-64 they are bolt on and a easy change out, 65-66 are one piece, and have to be trimmed out of the way, and use an earlier c10/40 bolt on mount
the transmission tunnel has to be changed out with the one from a c/10-40 (I did come across 1 64 c/80 that had an allison 5 speed, it had a low hump tunnel instead of the regular flat big truck tunnel.)

other minor things: save your c/10-40 column drop, some of the later big trucks still used the dual master cylinder/hydraulic clutch, like the 60-62 c/10-40,there is a support brace across the belhousing area on the c/50-80 that needs to be removed (unbolted).
here is a pic of the 2 cabs that won't work:

Thank you for the info this helped alot. In my area the smaller trucks are more scarce and the larger ones (grain trucks ) are more available.

That holds true around here also. The grain trucks are generally in better shape too since they're usually not on the road in the winter, sit higher off the ground, have running boards that protect the rockers a bit and usually are stored in a barn or at least a lean to.
