Hemi 4 Speed ID help

LOL You have to replace the input shaft and all the syncro blocker rings, both sliders, and gears (1st, 3nd, 3rd). See the "fine teeth" (dogs) where the syncro sliders engage? Those are not factory on yours.

What you essentially have there is a "crash box" IE a non syncro transmission. If you got real good at learning to double clutch I guess you could drive it, bit a PITA, I'd bet

See how fine the syncro engagement teeth are on these below?
