Hi. New to the forum. Just picked up a sweet 82 gt project, one of my "always wanted one" from my younger years. It came (not installed) with a posi rear end that is disc and 5 lug, from a 88 turbo coupe. Would this be a straight up bolt on application. Done alot of wrenching in my years just new to fox bodied mustangs. my last stang was a 68 fastback i restored 8 years ago. Somewhat simpler. Thanks much
