1969 Race Dart w/ 426 Hemi- garaged for 45+ years

The 833 4 spd would have been slick shifted or pro shifted back in the 70's. I don't think Liberty started faceplating the 833 transmissions till the early 2000's. I had Liberty do one in 2011 and they could only do 3rd and 4th gear, with 1st syncroid and 2nd pro shifted at that time. Some time in the mid 20 teens or later they started faceplating 2nd 3rd and 4th gears as best as I can remember.
