<VV> Seized Convertible top latch

My experience is with an early and long ago. As I recall, the early/late
latches do not interchange but the same basic design. So this should apply.
As I recall, removing/installing the latch assembly is simply the two bolts
as you concluded.
The J hook screws into a small casting. The small casting is attached to
the rest of the latch mechanism with a single pin. It is free to pivot on
that pin. There is a spring that pushes the small casting one direction.
There is a small lug cast into one side of the small casting. It contacts
another lug on the latch mechanism that causes the small casting to rotate
against the spring force as the latch handle is moved. This rotating action
is intended to bring the J hook into position as the latch is operated.
The most common failure I have seen is a broken small casting. The small
casting is essentially a clevis that is pinned to a single member of the
latch mechanism. When the small casting breaks, one side of the clevis
breaks off. My guess is that is what has happened to your latch. The
broken piece may have jammed into the mechanism keeping it from moving.
Removing the assembly from the car and giving it a close inspection should
verify this or let you find the actual problem.
Originally, GM only supplied the entire latch assembly as a replacement
part. Clark's catalog shows that they have replacement parts for the hook,
spring, and small casting.

Well I am pleased to report that I now have a fully installed Clarks Corvair
supplied convertible top on our 1965 RHD Monza convertible. A big job, but I
am very happy with the results. Not a wrinkle, totally smooth and I am
progressing well with the side glass adjustment (an equally frustrating
However, today when I was lowering the top one of the locking latches (above
the front windscreen) seized solid in the open position. The chrome hook
swings freely at an odd angle. I can lower the top but can’t lock it down on
I expect that the seized locking latch is either damaged (broken) beyond
repair and will need to be replaced or maybe it just needs re-alignment /
assembly? Either way I expect that I will need to remove the seized latch to
determine if it can be repaired or if it will need to be replaced totally.
The illustrations in the Corvair Body Service Manual suggest to me that
these laches are simply held on with two bolts and can be removed easily
without disturbing the top material. I certainly hope this is the case but
wondered if anyone has any advice on removing / reinstalling these top
