F/S or trade for running engine

[big blue 72]

I gotta get rid of the 71 rolling frame, half cleaned and painted and long bed with surface rust and one small hole in fender lip and 2 small holes over rear support. NO BONDO! bed is in very good shape having had a camper shell on it until this past summer. fender wells are solid and sides have only a few small dings, nothing major. would take $150 for the bed or $250 for both, but am willing to deal!
would like to have it gone before Christmas. Am looking for a running 307 or 350 to put in Big Blue which has a leaking head gasket and needs a rear main seal. Due to my physical limitations i cant fix either of these things. Also, anybody in the Cincinnati area that needs some work, I need a machanic buddy.
