I want stock spec leaf springs to replace the old worn out ones on my 1983 FJ60. Anyone try or have luck with these ? (the Toyota part numbers they reference are correct, but I have no idea if those physical dimensions are indeed correct for a stock setup) : 1981-1987 Toyota Land Cruiser 4 Door - Leaf Spring (Front - 5 Leaves) [90-112] | $178.95 | SD Truck Springs | Leaf Springs, Helper Springs and Suspension Parts 1981-1987 Toyota Land Cruiser 4 Door - Leaf Spring (Rear - 6 Leaves) [90-105] | $188.95 | SD Truck Springs | Leaf Springs, Helper Springs and Suspension Parts These are made by some company in Harrisburg, PA called Dayton. The rep I was asking to from SDtrucksprings to confirm OEM spec emailed the following info to match what was on their site: " Below you will find the specs for these springs from our site, Dayton, and Toyota. Front Springs 90-112: Rear Springs 90-105: The eyelets are 35mm on each end of the springs. " Do these physical specs look correct ? The part numbers I have verified already. Thanks in advance for any info.
