65 and down had the Hurst 66 they put in the Inland If you had a 65 with an Inland someone added it , they didn't use them in the 1965 model year and in 1966 they didn't use the 4 speed behind a slant 6
There are 2 mopar bells that use the A833 4 speed trarns and the slant. I don't have the cast #'s right here. I can't personally atest to what years they were used in but I do know it was early 60's cars,no doubt A's and maybe some early B's?
