77 to 78 TA shaker changeover

[Wallington]

Here's a notice with date and even models at the point of when the low-profile '77' TA shaker was changed for the larger '78' shaker. (still in 77 model though).

Wow, that is cool info for the 77 guys. You really amaze me with the info you find, even being on the other side of the world. Though the interweb sure helps I'm sure.

Yea that’s definitely cool. Something I’d only known about in recent years

Just sorting through some old Bulletins and Manuals. Lots of trivia and info but not always of interest to most. Some things like these don't pop up elsewhere though. This is from the 1977 Dealer Technical Bulletin. A few 77 guys need a copy of this in their glovebox at shows when told they have the wrong shaker!

Another thing to note is apart from the new, taller shaker assembly for mid-77, they also changed the shaker to hood seal. This needs to be considered when ordering the typical OER seal off the shelf and wondering why it barely seals or even squashes, and not just because it's OER.

Thanks for posting this. I always thought the taller shaker came out mid year, long before the actual issue date.
