new here old to Darts , had my first 70 340 in 74

Well that's great , had a 72 dart back in the day as well , turned it into a clone with 727 sway bar and 83/4 diff . Think the only diff between them is no boxed frame where springs mount , and for some reason the 70 series tires rubbed on the rear inner fender . Are the 340 swingers built with wider wheel wells ? Always drove me nuts as my 70 wheels tires would rub on the 72 .
Good luck with your car , if I part out things you will be on the list .
