Thanks alot 66fleetside! You clarified alot of the questions that i had. I have a couple more questions. I read a post somewhwere else where a guy tranfered a 75 suspension in to his 64 and only had to redrill a few holes for the idler arms. is it the same thing for the 71-72 suspensions? Does the 73 or later suspension transfer better than the 71-72 suspension? Thanks everyone for your help. i really appreciate it.
