Yeah, I think it would have been impulsive. Even my neighbors 72 lemans sport has a 12 bolt rear, I was wondering about that too. I will keep the Blazer, I do "need" to have a 4x4 all the time of course. Some day I will buy a GTO, but what I want is a 70 with ram air and a 4 speed, I just need to wait for the funds and be patient. Later all.
