1965 Dodge Dart Charger

Today I got the rubber mounting that I wanted. The cc between the holes is 1,81" or 1 3/4". What do you guys think of the height towards the rear valance? Is it ok or should it be higher or lower?

There is a small different in size of the rear clips that goes into the frame. I took the grinder and adjusted mine. This will go on the convertible.I might start doing kits for hanging the rear resonator!
