I was looking for a pair of SS Springs on Mancini Racing's site...There's a bunch of different ones with different weights... I weighed the 69 Dart and it was at 3240 so thinking the Duster may be a little heavier at 3300 or so. The springs are for a 72 Duster with a 416 and a 727. 8 3/4 rear and 4.56 gears. Which one would be the best to use? 3300 lb springs #MOP 865-866 or something different???
Something different than antiquated 60s technology would be my choice. Like a mono or split mono spring
