[SEL] More Rivet Pictures on Muffler

[Paul Maples]

Ok Gang I took the muffler apart today and got some more pictures and measurements. As you will remember here is a picture of the line of rivets on the outside of the muffler:

I measured the top of the rivet on the outside of the muffler shell and it is roughly 1/4":

Looking inside of the shell where the end of the rivet was bucked the head is roughly 3/8" in diameter:

As best as I can measure the thickness of the shell (single layer) using my vernier it is roughly .043 and I say roughly as the metal on the shell is heavily rusted. This would make the lap joint thickness about .086 or somewhere in there:

So now I need to select the right size rivet, the right length, the right staking and setting tool and get with it. There are 13 rivets. So now you rivet experts come through for me and fill in what I need and then I will try and get it. To get a rivet with the head you see in the picture do I order a special rivet or just use a special staking and setting tool to get the head design? Since the top of the rivet head is about 1/4" and the bottom of the rivet where it is peened over is about 3/8" what shaft size rivet would you suggest I get? And since the total thickness of the lapped joint appears to be about .086 thickness what length would you suggest I get?

Thanks for the help.
