    Anyone know how wide the K30 14B spring perches are? Say from outside perch to the outer side of the other perch? I tried searching for but for some reason couldn't find it. I know they have been posted before [​IMG]

    40.5" Center pin hole to center pin hole. This measurement was taken from a 14bolt from a '75 1t.

    Thanks guys, sounds like I'm gonna have to measure a lot closer. Guess this time when I go to look at these axles I better get some scrubby clothes on [​IMG]. I'm thinking it will be one ton though... just my luck I always get the stuff with the "BUT"s.

    Don't know if it's too late or not but my 14-bolt out of a 1985 1-ton is exactly 40" c/l to c/l; measured with the axle out of the Blazer. The spring pads are 2.5" wide &amp; located 5-5/8" from the back of the brake backing plate mounting flange.

    Hope this helps

    Captain, My axle is also out from under the truck right now and the old measurements are exactly the same as Brians above and they need to be changed to 42.5" Center Line for the Blazer/Jimmy springs to fit correctly.

    Thanks guys,,, It was just kinda tricky measuring under the truck so wasn't sure if the measurement I made was right but seems like it is a one ton.
