I am having these installed and the guy just called me to say that on the passenger side the 620LB spring just "rattles around" between the spring perch and upper insulator. He said there is about 1 1/2" clearance there and it will fall out on it own if left in. The other side is appears to fit OK. Any ideas? I have the Shleby 1" drop new uppers and spring perches. Lowers are about 5 yrs old. I also have new grab a track shocks all around but this is without the shock in there. The old springs were taller and thinner (no idea what they were though). Thanks I am leaving soon to go view what he is talking about. Any help would be appreciated before I leave.
