I swapped in J20 axles on my 66, but it was necessary to relocate the front springs.Phils67 wrote:Has anyone here swapped a J20 front axle into an early FSJ without changing the post style front leaf springs? If i am measuring correctly the cast spring perch on the main housing will interfere with the u-bolt when i weld the new perches on. The diff i am building is a 78 front passenger drop that was originally SUA and im going SOA. Just seems like ill have to offset the perch a half inch for u-bolt clearance and i dont want any issues when i go to install it. Feedback is appreciated

Trial and error. I will update as it goes. And yeah, sometimes i wish i had the newer chassis. Ive looked at some before and opted to just build what i have. Mine was still in saveable condition
