I have a 1950 Chevy Deluxe sedan with a 261 Jimmy for power. I want to pull 3 spd and stock rearend out. Replace with 4spd open drive line and s10 rearend. Question> Is there a bellhousing that will bolt to 261 and except the Saginaw 4spd? If so do I need a special clutch fork and throwout bearing? Any help is appreciated.
