108 wb versus 111 wb leaf springs

Ok now i'm well confused, I thought Dusters were 108 and Darts(except the Sport) were 111???? The year I'm talking about for my car is 1970. The reason I had asked in the first place is that I knew or thought I knew that Darts were 111 because I wanted to buy some prefabbed frame connectors from another FABO member and knew that the ones for my Dart had to be 3 inches longer than 108 wb cars. I had also heard once that you could force the 108 springs onto a 111 wb car but that it was a major frig and that the shackle hangers were in an odd position when you were finished.


Yes Dart Swingers and Scamps are 111WB and Duster,Demon,and Dart Sports are 108WB. You are correct on the connecters as the extra 3 inch is right around the back seat leg area.

The springs area is the same for both though. They do not use different spring lengths.
