1972 Duster , starting to tear into the build

Worked on welding all small pieces for fold down seat and test fitting all the other pieces , so far so good , need to work a little on my angle for the rear piece of wood and may have to make a new piece as previous owner cut speaker holes up high an to close , I dont mind putting speakers on it but I want them spaced differently an more centered , but will see,,I want to find an old school Pioneer KEX-20 GM-4 AMPLIFIERS,Kp9600, K20X. EQUALIZER components and some good triaxial speakers in the rear and some others in front
if I can find as that's what I have in my old challenger and old Pioneer is one of my favorite stereos for these old cars
