Was wondering why did they make an 8 3/4 with the big and Small yoke? what are the pros and cons.

The only true answer is probally in Mopar decision makers corrosponces All the early cars, 1963 and earlier had the 7260 rear joints, ball and trunion front joints of severl difference sizes Once the 5 year 50,000 mile warrenty was started in 1962 or 1963 it probally made since to make parts stronger, especially with the HP wars, race on Sunday, sell on Monday and pony car wars started. The beefeir parts where probally put on the cars so they wouldn't have to replace them under warrenty and pay the dealers shop mechanics to fix them, as well as seeing cars break parts at the track wasn't good advertising either
