69 cab... 78 frame??

[cr480r]

Anybody have pics of the body mounts involved? how high must it be lifted to work? I also thought maybe the rear mounts could be channeled but I dont know if I could do it and still keep the fuel tank behind the seat.. would the '78 rad support mounts be usable?? My 4wd 78 is in need of a new cab and I can get a pretty solid '69 C20 cab and clip for near free.. The 78 is a swb with a flatbed so wheelbase differences/bed alignment wont be an issue... i just dont want a huge body lift...

Any info, photos, or links would be appreciated..
