Had to dig, but here is original and new one I put on in 2016. FYI, alt bracket bosses and pwr steering bosses were just off enough on the new one to be aggravating! Also an additional hole on new one.
That will interesting if you can find out any info based on the casting numbers.
'67 Part book shows 2 water pumps available for the 273
2448 315 w/o CAP
2585 385 w/ A/C, w/ CAP
Part numbers also show different impellers. With A/C might have had 6 instead of 8 vanes, and maybe a different pulley set.
That always sucks. I must have at least 3 aluminum LA ones on the shelf that failed in one way or another. I returned at least two A1 Cardone rebuilds one year. Well not quite, one never made off the parts store counter. LOL. Currently using Edelbrock's - nicely made, but required a little grinding to because of contact interference. I got so leary of rebuilt water pumps I was looking at sending my jeep'
s out for rebuilding. Found a couple of places but so far the aftermarket one is working.
My friend sent me a photo of an aluminum LA pump for the early (driver side) pump inlet. It was posted on FB. Unfortunately no info on who made it. Kills me that no one is making one today. Even for my Wagoneer, two companies make aluminum versions. One of 'em fits too!

For sure don't use the later aluminum water pump. I did in my 1965 Dart 273. My mistake was because I could only get a radiator for a 1972 at Autozone and the alum pump had its lower (inlet) port on the correct side and was 1/2 the price of the correct cast-iron pump. I was a newby then and not using ebay. The alum w.p. is 1" thicker, which required changing all the pulleys, and no brackets for my TRW p.s. pump (had to change to Federal p.s.), plus it moved the fan too close to the radiator to use a clutch-fan.
The main choice in cast-iron pumps is 6 or 8 blades. They used 6-blades on factory AC cars (at least in A-body world). Best we can figure is because the pulley diameters varied, because wouldn't everyone want max water flow? The one in post 25 is for a non-AC engine (i.e. pulley set). There are many variations in pulleys, even within the same year. Google Images will help you.
It's not that tough to accomplish what your after, My 69 Dart uses the original 273 with A/C 2949069 which is a 3 core radiator. I had the radiator shop move the lower hose connection from the left to the right side, had the radiator rodded out. I'm using the the pulley system from a 1970 and newer. I did use a 2785614 fan shroud and the MP clutch fan package. This is on a healthy 360 w/ Dynamic 3200 convertor with A/C ( old style Rv-2 comp.), P/S, P/B. It runs 190 with A/C on in Florida heat in traffic.
