I'd have to look, but I think the 5-7 motor mounts the opposite way it's shown in that picture, the side facing out would be toward the front of the truck ... the difference in the 8-9 motor is in the way it mounts as well as the arms, the 8-9 vacuum motor was different than the earlier one too, bigger .... probably if you got a correct 5-7 motor the radio would be OK, and you'd also need those 5-7 transmission arms from the vacuum motor ... I can't find a pic of them right off, but can prolly get a shot tomorrow from the parts stash
