[Healeys] BN7 Top Frame

Only one 2-seater top frame for BN6 and BN7, sorry.  

One would have to see your installation, to see what the issue is.

The bows have an adjustment, two long screws in the feet of the main bow, but that would likely not affect your problem. Nor would the separate thin wedge piece under the clamp

The aluminum trim and rubber seal together should have enough thickness to get a nice over-center action from the clamps.

The wood bows from Moss have sometimes not had the correct curve to fit the windshield top exactly, in my experience. If the bow is not curved enough at the outer ends, then the clamps are too close to the pegs.  Look very carefully at what is going on, and see what would be necessary to make the wood header bow provide enough height from the windshield to raise the steel top frame, and make the clamp just barely reach the peg at full extension. Maybe add a strip of 1/8 plywood between wood bow and aluminum ?

Attached pic shows "J" hook fully wound in, so rubber seal is removed for replacement with new. The lovely sharp-pointed "S" clamp is the correct original BN6-7 type, but the blunt BJ8 "safety" clamps sold now do the same job.

Best I can do without seeing yours.
