Repro - review, Dynacorn Conv Top Frame
« on: February 18, 2011, 05:03:59 PM »
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?
