I went to the junk yard today and came up with a few numbers but nothing is very close to the stock cruiser springs...
97 Dakota 2.5" wide, 55-56" long with a 24" from hanger to center pin
99 ram 1500 2.5" wide, 58.5" long centered pin
92 chevy 1500 2.5" wide, 64"
95 S-10 blazer 2.75" wide, 51" long with 27" hanger to center pin length
90 explorer 2.5" wide, 56" long, and 26" hanger to center pin length.
88 Bronco II 3.0" width, 55.5" long, 26" from hanger to center pin
93 ranger 2.75" wide, 56.5" long, 26" hanger to pin length
87 ranger 2.75" wide, 56" long, 25.25" hanger to center pin
81 T/A 2.75" wide, 56" long, 25.5" hanger to center pin.
then I came home and measured my very damaged cruiser front springs.
driver side 2.75" wide, 43" long, 21.5" hanger to center pin (military wrap end to center pin)
passenger side 2.75" wide, 43.5" long, and 22" from factory shackle end to center pin.
I figure my measurements are all within .25-.50" +/-, I was using a steel tape so it didnt flex great.
I am attempted to try another set of cruiser front springs and keeping these as emergency backups, but flipping the others to where the military wrap is at the front / hanger side and hoping they stay together, maybe add an additional strap front and rear to hold em together better from the start.
Still open to suggestions and other options and measurements.
