A four headlight truck is basically a holdover 1964. So dimensions would be same as earlier. Does your truck have a nut on the end of the axle shaft?

OP: '72 was the first of the new body style and had one-year-only front end suspension parts, so the fact it's a '73 makes it more desirable. As far as bed style, the short wide bed is in demand, too. I wouldn't stop the deal over a bed style issue. The truck is 44 years old, they don't come around in decent shape that often.
I looked at an '84 from desert SW and was disappointed to have floor rustout. I was told here that that's common as drains get plugged and water gets inside. It's not a deal killer, but is something to check for.

Thanks dogdays! I'm not totally against the wide bed but it's the one part of the truck that is damaged and I always wanted a stepside. Although, after some searching, it seems that finding a nice stepside bed may be a bit difficult, so who knows.
Some real good info here though! I'll post pics here if I'm able to get the truck from my buddy. Thanks everybody for the help! You guys rule!

Step side beds do seem to be scarce when your looking for one.

I had one shipped in from Iowa years ago. Rust free some dents and a few extra holes in it.

When I sold off my lil red and warlock parts and put the bed on Craigslist for $500 I received zero calls over several months. When I was moving I broke done and called a fellow dodge truck enthusiast who took it off my hands for $300.

Kind of frustrating as I was able to get $750 for a nos box side but no interest in the complete bed.

About 45% of the SWB runs were step-bed during the 70s
Metal floors started in 81, The company that pressed the sides for dodge was the same one that pressed the Chevy step bed sides, only difference is the ridges that Dodge requested, they were located in Kansans went out of business when GM went to the flare style plastic beds.
Bed sides are the same from 55-85, bed got wider sometime in the late 50's.

Aaaaaaaaannnd, it's all mine!

I notice an exhaust pipe poking out in front of the rear tire.
Where is the gas tank? Behind the seat?
Or is it one of those Heart Throb under the frame deals?
I am wanting to put duels on my 78 and am not sure just how to go about it.
Probably going to move my tank into the bed.
I have a behind the seat tank,
However, I'm not sure I wanna ride around with 20 some gallons of gas in the cab, behind the seat.

Starting 1973, all V8 cars and light trucks came with front disc brakes.

Not 4wd trucks. 1975 was the 1st year for discs on them. The 74 Ramcharger may have had discs though. I'd have to look it up.

Soopernaut is correct on the trucks, I believe. My '73 W200 has 4 wheel drum brakes. Can't remember if the light trucks might have had the front disc option, though.

My little d100 has factory discs in front.

From memory the discs were required starting in 77

In case you wanted to lower yours heres a really good looking truck. The "Tin grille Dodge Truck" group on facebook is pretty active and always has stuffer sale on it.

Sharp truck

Disk were standard on 4x2s starting in 72 (drums were an option)
4x4s disk were standard on ALL models under 400 series the heavier series had drum in till the SEG (special equipment group) closed shop
After 35 years and parting out/scraping over 250 of these trucks I have only every come across 2 post 71's 4x4s with disk one was 72 W200 and the other was a 73W300

Rail stampings were identical between 4x2 and 4x4 only the X-members were different.

No Dodge 4x4's came with disc brakes until 1975, except the 1974 Ramcharger.

short beds are 6.5 feet long-----when you drop the tailgate that 4x8 sheet of plywood sits right there on the bed and tailgate---nothing hanging over the edge.....

I bolted a 1961 dodge stepside bed onto my 74, and swapped beds between a 1975 Sweptside and a 1980 Stepside. 100% identical fit.

That’s sweet! What mirrors are those? and the air dam looks nice too, did you make it?
