49-53 trucks had a 2 piece flat split windshield. The rust spot on the fenders is where someone thought it was a good idea to place a flat plate to catch and hold everything against the fender and firewall, directly behind the front tires, and call it a fender mounting plate.

A 54 to mid year 55 has a curved one piece windshield with angled front pillars. At least they were smart enough to change the fender mounting bracket. The windshield is hard to find and expensive.

A late 55 -59 (or 60) had a curved one piece windshield, but the pillars were straight up and down resulting in a wrap-a-round dog leg in the windshield. The glass for these are much easier and cheaper to locate. 55 & 56 shared the same body parts, a 57 had unique fenders and nose piece, and 58-60 had dual headlights with shared body parts.

51 & 52 were among the highest production numbers for Dodge trucks, up to the body change in 72!
As with any Dodge truck, missing body and trim parts will be hard to find. It was not uncommon to have the bottom of the doors rusted out, expect to have to rebuild your own door bottoms, no one makes sheet metal parts.

I've seen prices all over the ball park, but decent mostly complete trucks seem to run between $1,000 to $2,000 range, the nicer they get the more they cost. Paper work is often a challenge, so be sure you know what has to be done to title a truck in your are if there is no paper work. Also, it is not unusual for late production year trucks to have paper work for the next year. I have seen several split windshield trucks titled as 54s. Gene
