A quick look at Dougs, Hedman, and JBA shows no obvious changes on the products I can recall.

Being late model focused I'd think JBA would show most of their product line completely gone, but can't find any big changes.

Taking a wild guess it was probably a Sentinel Capital Partners (Holley Ownership) cya thing rather than The Man Keeping Them Down.

In the same breath I'll say Hedman's cataloging is super outdated, they still show F body headers not interchanging to M body
and things like that. Not showing vehicle coverage in your marketing is lost sales.
