Bow Dimensions*If you're stripping down a convertible top, we suggest measuring top bow dimensions to see how they compare with ours. What matters most is a top that will fit perfectly when it's time for installation. There are specified distances you need to have between top bows for good fit and function. These measurements aren't center-to-center, but from trailing edge to leading edge. Here's how measurements stack up.
No. 1 bow to No. 2 bow: 16 1/2 inchesNo. 2 bow to No. 3 bow: 16 3/4 inchesNo. 3 bow to No. 4 bow: 15 1/2 inchesNo. 4 bow to stainless molding: 20 1/2 inchesNo. 4 bow to drain trough: 22 1/2 inches
If you examine your '65-'73 Ford Shop Manual, you can fabricate a bow locating gauge from plywood, which will enable you to position bows to factory specifications.
Top adjustment isn't all that difficult according to Richard Smykay. There are five ways to adjust the top mechanism:Bow No. 2 up/down adjustmentSide rail camber eccentric at balance linkSide rail camber set screw at hingeHeader to side rail adjustment (fore and aft length adjustment)Frame bracket to body bolts (side to side adjustment)* Information courtesy Richard Smykay at firstname.lastname@example.org
