radiator purchase help I6 292

[sventinker]

So I am in the need for a new radiator for my 1970 c10 manual trans 292. I bought one from Rockauto and in the drawing it appears to be shaped like a traditional brass/copper radiator. It is not, it looks like the $130 specials that are flooded on eBay. It is an osc 368 and it came in in good shape but cheap as hell looking it is longer than my stock unit and the places where the brackets hold it are too far apart and not rounded. so it wouldn't fit if I wanted to. Where can I find a radiator that will just bolt in? I don't need a transmission cooler but they all appear to have this. I appreciate any help.
