I just went out and looked, seems like the extra hinge would not require a different cab or door and could be added later. How about the latches, my truck has three separate latch spots. Makes for a pretty secure closed door

From my build sheet the cab service assembly is part number 2QSA 492P14. It doesn’t show a number for the doors, anybody have the “cab service assembly” number from a two hinge door? It is shocking how many categories there are with individual part numbers, indicating there were options for those parts.

The only thing missing is what color was the cab originally. The frame seems to be yellow

Just got an email back from the Mack museum research dept. I highly recommend using their form to request factory records. It is free(I made a donation after getting the info though) I got a eight page chassis build sheet for my truck, info on where the truck was shipped(Denver and then grand junction) pdf copies of vintage catalogs and pricing (standard chassis price was $17520 in April 1953). Also they included 11 pages of parts suppliers! Interesting the serial number listed from the first sale and before Richie bros obtained a New number for the state of Colorado (what I used for the record search)is called the chassis number is LJ2DX5210D, the order number from the Mack paperwork is LJSWX1550

I think it is typical of a truck that was used for several different jobs over the years in industries that had motivated people willing to innovate to get the job done. It’s definitely been hot rodded trying to get more power and gears, air filter put outside the engine compartment in front away from heat, or lubrafiner out front to remove heat, crazy coolant bumper, whatever it’s purpose it took some time and skill to create and at least dissipates heat. If it was cracking they welded it, bolted it or wired it. Safety and liability don’t seem to be at the forefront. Weight didn’t seem to be a concern, only brute force. Get the Job Done!

It’s been long closed but we ate there after church on Sunday’s a lot

I highlighted the coolant line to the bumper with yellow and circled the device in question at the front right side of the engine

Engine shots and Showing the bumper plumbed into the coolant. What is the device on the right front of the engine?

Here is the right side front axle and spring shackles. Looks like it was welded in, probably messed up any original numbers

Good call!! NTC 335. I thought they were all intercooled

It is plumbed into the coolant, definitely to hot to leave you hand on after it is warmed up. I’m thinking it is acting as an overflow
