ok so i was talking to a buddy of mine, who has a 79 cutlass calais, and i was telling him how i want to put an 8.5 rear end in mine, he was telling me that the s10 blazers had an 8.5 in them, and its the same size as the g-body 8.5,.. all i would have todo is remount all the mouts from my 7.5 onto the blazer rear end,... i want to know if that would really work, and if its worth doing
