Converting an automatic 74 Swinger to a 4 speed

I bought a TKO 600 kit from Silver Sport transmissions, $6081.00 Complete kit, still had to buy a 4 speed cover for the console repop $ 400.00. Oem mopar dust boot around shifter handle $40.00
Cut out tunnel, make new tunnel, make brace to connect frames back together, modify the console to fit bigger tunnel. It's time and money. Oh forgot you have to add the pedals, that was fun. if you have a trans speed sensor and you want to used factory speedo you need a electronic cable drive unit, on and on if you do a TKO kit.
The old 4 speeds would be a walk in the park to convert to. My $.02 worth.
