Ok....I've owned ALOT of square body trucks ranging from half ton short boxes, to crew cab long, blazers, suburbans, etc. One thing I have never owned till today was a K30 4x4 regular cab...cab and chassis.

Most will say "okay? and?" well here is the twist I have never ran into. The truck is a regular cab, single rear wheel, 4x4, D60/14, T400/205, 4.10s. All good, great, very happy. Here is where it gets weird....the wheelbase. It is around 4" longer between the cab and axle, and an additional 4" or more off the back of the frame. Truck was a fire rescue with a service body on the back, frame has not been stretched anywhere.

This is going to be my full out trail rig and will more than likely get a crew cab set onto it in the near future and looks like it should work out perfect for me. But still stumped on the length etc.....just curious more than anything.

The standard duty 2 door C/C frame (309) came with a wheel base of 131.5 inches:

The HD frame series was available in two versions - both with extended wheel bases (310 & 314). It would seem that you have a heavy duty frame with the "less extended" wheel base (310) of 135.5 inches:

The frame dimensions and where the extensions were added are shown on this dwg:
