Trikebent's 40/46 Project

[Trikebent]

Well I did it. I bought a project.
Cab is a 1940 3/4 ton by the tag (KE) Front Sheet metal is 42-46. Rear fenders are 5 bolt (fender to sides) Real solid cab, 1/2 ton bed that's in pretty good shape Front sheet metal looks pretty solid as well. The grill is almost perfect. Truck has an updated rear end (GM style with a 10 bolt cover) and a independent front suspension partially installed. I don't know what it is yet, It has a Manual rack and pinion. Wheels are 5 lug Chevy S 10 I think 5 on 4 3/4"
Nothing is bolted to the frame at this point.
First step is to bolt the cab down at the stock height and see how well I can get everything to fit. I read that the 40 cab is 2" shorter, so I want to see if it all fits.
I also need to see what the wheelbase is as it sits
