In 1978 all of the engines and trucks delivered that year were equipped with electronic sirens. After looking at dozens of photos of '78 Mack pumpers and tower ladders, I can't see any speakers for the sirens. All of the Seagrave trucks that year had the speaker sticking right out in the front of the cab as were subsequent Macks. My question is, where the heck were the Mack siren speakers situated?.
