D/C I almost feel bad saying this but it went in from the bottom with plenty of clearence, the worst part was tightening the nuts for the wires, there on top on the mini .
On the 74 I still can't believe I did it through the mud flap hole, large one out & mini in, guess the headers are a different brand on each car, didn't look possible that way on the 73, anyway there both 360 cars thats the big difference, maybe a different brand of headers might provide better clearence? Rich.
