Can someone please tell me where the oil pressure switch goes, on a late 70's 454? the only place I can see that it would possibly go, is right above the oil filter. the previous owner of the motor had 3 adapters screwed in there, getting smaller as they go...and that's it. if I take out the smallest one, I can screw the pressure switch into the next one...but it seems like it sticks out really far, and it just doesn't look right to me. if anyone has any pics of where and how this should be mounted, that would help a lot. thanks.
