Roadking53, My 59 is no where near together so bare with me. Looking at your pics someone has added the mounts to the radiator core support. The radiator they used looks to be from a mid 60's C10, not that it matters. The good news here is that they didn't cut the core support and the factory mounting hole are still there. Once you remove the existing mounts you should be able to bolt up a factory style radiator with no issue. I chose a cold case because of the reviews and how well it was made, it has some great welds and heavy construction. There are plenty of radiators out there that will do the job just fine. I would definitely use a shroud if you're able to, it will aid in cooling and direct the air flow through the radiator. I see a lot of trucks without shrouds and they seem to cool fine, I just bear on the side of caution. Living in the South you know how hot it can get.
I used a 17 inch seven blade fan and a fan clutch as these were what GM used on the Camaro with the 327. Now please understand that I made my own motor mounts and located the engine farther forward. I don't know if you will have the clearance needed for a fan clutch or if you will even need one. If your 283 is in the factory V8 location a fan spacer may be all that's needed. I would mount your radiator and do some measuring.
As far as the alternator bracket is concerned look at Allan Grove Products (Vintage Air their his mounts) they have mount to place your alternator in any location you choose. Hope this helps, sorry I don't have more pictures of the radiator mounted but as I said it's no where near complete.
PS: Look at my Build in the Projects Forum, I have a lot of pictures posted there.
