I'm looking to upgrade my rear leafs. but don't want to go and purchace any.. the reason i don't want to purchace is I have access to a junkyard. I work at one. I am trying to find out what other type (chevy , ford, etc) rear leafs will cross with XJ leaf springs.. if anyone can give me any info it would be a great helpto get the Junkyard Dog up and runnin again....
