Ball n Trunnion Boot help

[jabdusty57]

I ordered a BnT replacement boot kit Q-112 from oldmoparts.com but the new boot looks nothing like the old boot. I have a 64-65 833 so I assumed the BnT joint was from the same year. Can someone help me identify what I have?

Detroit ball but the way they have those listed i have no idea which one of them you need
The Detroit ball head parts go by pilot dimension they have nothing but years listed and many years use more than one version of Detroits ball.

I would have it converted, see you're local driveline shop
