I've got a 12 bolt out of a 70 impala been setting here for awhile curious if it'll work in my 79 Malibu I know I've got a 66 chevelle 8.2 10 bolt in my car know running iceman upper and lower control arms the impala rear will have to be narrowed I know and ill be buying axles etc so bolt patern isn't a issue I guess the main issue I'm concerned about is the upper mounting ears the same as my 66 chevelle rear? So I can use my a/g body upper arms ????
