Thanks to idrivevintage I now have a unused original for my Dart.
WOW I remember them from the old days. I bought my first Mopar a new 1974 Duster 360 from Paddock Chrysler in Florissant, MO.
1970 FE5 Duster 360/904/3.91's SOLD
1973 TB3 SpaceDuster 340/4spd/4.10's SOLD
Moparless for now but when the opportunity is right I'll have another one.
