As far as I know, All E bodies 70-74 will use the same bolts .
It doesn't matter if it's a Phillips , a Motorola, or a Bendix ,
AM , AM 8 8track , AM FM, knobs or thumbwheel, all E body radios use the same
bolts . They are unique to E body , due to the size, not found on A B or C .
I do not have any extras laying around at the moment.
