Picked up a Dynacorn top to compare to my '68 and a few earlier odd parts I have for the top frame.
Overall a very nice part. It does vary quite a bit in detail from the '68 I have, and in some ways from the few 65-67 parts I have lying about. But it looks like it would install very easily and function as good as OEM.
Two key differences:
1. Bow #2. The camber of the bow is very flat, much less curve than my '68. It also has an eccentric for up and down. I have heard that early 65's used a different bow, and am wondering if this flatter one is based on this engineering variant, not the later version (no changeover date known). I think the eccentric is just an add-on, a nice feature as it locks better than the slot style used on the OEM's (all 65-68, as far as I know).
2. Bow #4. The curvature of the bow is different, and the "shoulder" is lower than the 68. Again wondering if this may be a change from 65-66 or to 67-68 as most top manufacturers list a different bow height for 65-66 and 67-68. As my 68 sits about 1/2"-1" higher I'm again thinking a change between the years? But this is odd as the repro is lower than my '68 and most top vendors call out a 21" height for 65-66 and a lower 20 1/2" for 67-68..
?
Anyone ever compared either of these two parts between an early 65 or 65-66 and either a 67 or 68?
