I have asked many questions here and I promised when I finally had some advice I would share it. Well, I finally do. I spend all weekend removing the rear suspension/motor and trans from my 54' chevy 4door. As most know they riveted alot of the brackets in. Instructions are usually to drill them out. I came up with a better way, I think! This could be common knowledge, but it worked great and was less work, and than drilling out rivets, and killing your drill bits in the process. First you take an angle grinder with a thin disk and slice off the head of the rivet flush, Then take a center punch and a Pneumatic Palm Nailer and zap them out. Worked like a charm, and I didn't have to kill any drill bits. I know that a Pneumatic Palm Nailer is not a common car tool, but if you have one they work great for this, they also arent that expensive, and you don't need a giant compressor to run. You are also left with an intake bracket that hasn't been drilled off center. Sorry if this is old info for some, but I though it was a pretty cool way of getting rivets out.
