I’ve done it with a manual charade and it’s fairly straight forward. The charade pedal box fitted no worries you just have to drill out the mounting holes in the firewall, they’re stamped just not drilled. Have a look at my thread 1993 G201 Detomaso there’s a pic of the firewall and the pedal box. You need the manual throttle body, speedo cable, front crossmember, wire the neutral lockout, remove the grounded ecu wire that lets it know it’s an auto and a few other small things i’ve probably forgotten.
