I'm getting my 81 GP on Saturday. I'm new to the G body world & found out about the Blazer conversion last week, then saw this thread. I'm less than 1/2 hour from there & I don't **need** these but I feel like I should go get them.?!? This old thread lists tools needed but was unsure of some sizes. Does anybody know exactly what size tools are needed? I don't have anything yet, but can get what I need...
