Radiator advice please

[belldar]

My 6.2 diesel radiator for my 88 1-ton build was shot so I am looking for other options. I would like to find something really close or the same as the 6.2 radiator that was in it. I am building a 496 for the truck to replace the 6.2 and would like at least the have the transmission cooler part of the rad for my TH400. Also wouldn't mind still having the engine oil cooler my 6.2 rad had! Going with a larger oil pan but the more capacity for the 496 I ink the better, but not a deal breaker.
There are a lot of aftermarket rad companies out there and I am not sure who to go with and can not find a strong enough( at least in my opinion)factory replacement (aluminum/plastic) to fit. Do I special order one or hope to find a decent 454 rad with trains lines?
The truck will be a torque monster, not much pulling, badlands hunting, maybe a few mud runs truck. Don't want to have regrets but at the same time don't want to bust the bank!
Thanks!
FYI the truck in question is the one in my sig
