My 14 bolt and 60 came out of a GM 1 1/4 ton military pich up.
The 14 bolt, center to center spring perch measure at approx. 40 1/4 inches and i was able to use the factory GM perches that came on the 14 bolt. They lined up PERFECT to my factory Jeep hangers and shackle locations.
The front 60 i don't know the measurement but i out boarded the hangers 1/2 on either side, along with a 6 inches frame extention and reversal.
Good luck with yours
