75 duster 383 implant

Welcome! The column shift will hook up, but headers won't fit then.. most go with an aftermarket cable floor shifter (at least I did) for simplicity sake.. the factory floor shifter requires cutting/welding the tunnel side rod bracket shorter

This is what I'd get if I did it again -
Trans Dapt swap mounts ($100 cheaper than Schumacher's)
Schumacher motor mount shim kit, and torque strap
poly trans mount
Your preference cable floor shifter (I got a NIB Hurst Pro-matic2 off eBay for $120 shipped)
Schumacher, or TTi headers
