The late 47 thru 54 would be a better fit with their wider cab and fat fenders. The 40 cab makes a nice fit on the back corners but gets tight at the front. I have about two inches of the S10 frame peaking out on each side at the front corners. The fenders will cover that up though. The bigger issue is the hugh amount of space left between the back of the engine and the front of the cab. The clutch fan extends about five inches forward of the radiator core support. I got a 16 inch wide radiator made that I can stick way out behind the grille but it's gona look like Frankenstine under the hood if I leave it like this.
