If you need to know what you have or need. Here's some helpful info.
Measure the depth (front to back) of the radiator area that fits into the saddle. It is either 2-3/4" or 3-1/2", you'll also need to verify which saddles you have... measure the indention in the rubble piece in the saddles/mounts. they should be approximately the same measurements as above.
The radiator for an A/C truck is no different than non A/C, other than an A/C radiator is always a 4-row, that requires 4-row saddles (bottom) and 4-row hold-downs (top) they are the 3-1/2" long at the rubber mount, as opposed to 2-3/4" of the 2 & 3 row radiators. Although you can run this 4-row Radiator anytime extra cooling is needed (Big Block also had the same 4-row radiator stock.
Now, If your running A/C, The A/C lines run thru the radiator support, and there are pre-drilled holes for the lines (or maybe could be drilled) and the A/C condensor mounts in front of the radiator and in front of the support (on the grille side)
The only other variation from this is the 6-cyl radiator, it's narrower. Only about 26-3/8" wide, measuring only the core width, it's a 2-row core. All V-8's, whether its a 2-row, 3-row, or a 4-row are all 28-3/8" core width. But, if your going from a 6-cyl to a V-8, you just need to relocate your saddles and top mounts on the passenger side out to the next set of holes on the radiator support. and use a 28-3/8" core width radiator. Either a 2,3, or 4-row of your choice.
Although some people don't have a fan shroud and it works fine, I recommend a factory or aftermarket fan shroud. It creates a tunnel that the air is pulled thru, Air flow is a large part of the equation in cooling. So, use a fan shroud if possible. no, I don't sell them. Sorry.
Ok, that's enough Blah-blah-blah....
PM or call me at 605-341-6634 M-F 8-5 MT with any questions.

But the radiator core support is the same right? Only the radiator and brackets change from 2 to 3 or 4 row?

Fan shroud huh? Thanks! I may look into one of those. While I am fixing mine up I might as well do the best fix up job I can.

I have a 2 core radiator with a factory shroud. This weekend I'm going to drop a 4 Core in. I have the Correct Upper and lower brackets/rubbers.

Will my current shroud bolt up on the bottom? seems like ill be spacing it out with the bigger radiator and there will be a gap. Guessing I could just use spacers on the bottom to take up the gap.
