Hood Latches for a 1929 Twenty

I imagine it has been discussed before but how many types of latches were there for the Twenty. My '27 doesn't have any side panels (I plan on ordering a set) but it does have what I believe are part of the latches. On the lower dust shields are upside down J looking hooks which appear to be forgings that are riveted to the shields. Is this an early, late or no type of factory part. Thanks for any info. BTW have the cylinder sleeved, new rings installed, exhaust manifold fixed and heat stove pipe between carb and heat stove fixed now.

have you looked here about the latches http://www.acmoc.org/bb/showthread.php?16097-Twenty-hood-latches-early-style

You have the early style latches.
