Converting an automatic 74 Swinger to a 4 speed

New TKO 600 5 speed with 3:73 SG and 5.7L Hemi with 333.0 HP and 371.9 FtLb on rear wheels is fun to drive.
I get fpg now (Fun Per Gallons). That bent up over shifter sticking out of a console is awesome.
I hope the OP goes for it, he will forget about all the trials, troubles when he dumps clutch in 1st, and bangs 2nd and hold on.
