I loved my 71 Duster Twister with the slant 6 which my parents gave me when I went to college in 78. Very slowly started falling apart but I didn’t really need a speedometer anyway. The self starting horn and accelerater made some fond memories.
These Chrysler products sure had some quirks.
On several I've had to remove the horn sensor, which was two strips of metal separated by a layer of foam in the center of the steering wheel.
Then one day it would not start, despite checked out battery, solenoid, starter etc. Turned out that the starting current passes through the high beams floor switch. If this switch is never used (my car was in LA city) it eventually forms an open circuit. Remedy: switch the high beams on an off once. Then it starts.
