A-833 OD transmission what type is mine? 421,422??

Where are you getting your linkage from? not sure about 421 or 422 type. You have what looks to me as a nice O/D trans small output, small front bearing retainer that should work with your 65 bellhousing. The O/D linkage from Brewers should work with the 6350 mounting pad, and a MOPAR Hurst shifter. What shifter and linkage do you have?

i came across this hurst kit Hurst 4 Speed Street Super Shifter Kit Mopar A Body A833 Type 421

but i really dont know much about, it's my first manuel conversion im used to automatics. so i will take all the help i can get.
