> [@97FormulaWS-6](#): > > 1980? I think those were 8.5" ones… Negative,all 1978-1983 were 7.5’s. A common swap for malibu’s is the GN 8.5 and a 12 bolt. ---

the 80 malibu is the “new” design of the malibu @ that point, whre as the 79 & 80 f-bods were still the “old” bodystyle at that point, which could be the answer about that ---
