Bob...I've seen these charts before. If you look at them closely they appear to have contradictory information about cars and rear axle lengths...one for sure are those that mention Monte Carlos and Big Chevys. Anyway..Monte's are about 57-58" wide in early 80's. I guess Im concerned about ending up with too much backspacing of rims so want a good "drop in axle" if anybody knows of one. 39's were shorter and thinner than 40's. Plymouth in 40 made a body/frame change form earlier models a best a I can make out.
