Anyone have an original 69 L/78 with THM400 ?

Worthy of note is that not all SHP bb/TH400s used the solenoid set up. The best known example is the L89 car tested by Popular Hot Rodding April '69. There is a clear engine photo showing no solenoid. Super Stock also tested a automatic ZL1 [#5?] that did not have it. The solenoid seems to be a late production addition, do not know for sure.

In your examples, what would constitute late production?

Now that you mention it, I do recall having a discussion
about this some time ago and what I recall ( now ) is that
not all L/78's w/THM400 got this solenoid. It was never
couched in the context of early vs. late production though.

Can anyone else verify this or comment further? There must
be some L/78 owners out there with survivor-like cars that
can shed some light. Would Chevelle vs. Camaro vs. Nova all
share this early vs. late production difference?
