Hey stone4X4, do my eyes decieve me or is your truck a first gen 4wd? If that's one of the trucks you swapped a 5m into where'd you put your radiator? That's probably one of the biggest things keepin me from goin with a 5m in my '80 4wd is I've been told there's not enough room in the older trucks to stick the big six, but earlier tonight I started thinkin about cutting out the core support and stickin it in place of the grill. Ideas? Nate
