1976 three on the tree question

Back in the sixties a 3 on the tree was common as dirt in poor mans cars and pickups, no matter what brand.
I have a 62 Lancer, a 64 Savoy more door and a 62 Dart, all were slants and 3 on tree cars. A230.
My second car in HS was 64 Ford Custom, 289 3 on tree. I had a '68 Ford 1/2 t. 289 on tree.
