Thanks for the replies guys. I feel a single round headlight not only looks cleaner but lends itself more to the overall rounded lines (stepside)of the truck. Then, of course in doing the swap LED's will replace the sealed beams so visibility shouldn't be a problem.
I could've sworn the truck at the junkyard I pulled the buckets from had the same 79 grill as me, just someone had already gotten the bezels. I guess I'm just asking because I want to know whether or not some of the nice pieces on eBay can be a go for the swap before ordering a pair.
