Air Shock Question

I ran them to get a 10 inch wide tire on the back of my 65 in 1985. had to pump them up to get the lip off the tire. 3" Shackles out back too. Hey it was the 80's! The shreader valve was bolted through the trunk floor right in front of the trunk latch. Needed shock extensions bad. I didnt know **** back then, got it like that.
