I bought a rivet set and made a buck to clamp in the vise and had a friend hold things in the right place while I set the rivets.  You'd be welcome to borrow the set....don't know where the buck tool is, may have just been a bolt...just as soon as RTM could send it to you.

Got a pic of what is being riveted?

Thanks Bob, If Wand wants it that's ok with me.  He can return it to you and I'll get it when everyone is finished rebuilding vent window frames.  I presume you have a handle on how I used a plain rivet set in this application.  I probably didn't explain it too well for Wand but so far mine is staying glued together.

A modified C clamp works well like Rudi said.  That's how I did mine.  

This might be the way to go.  I can go to harbor freight and get some crap cheap c clamp for $5 bucks that I can drill out or modify some how.  No way I am spending $150 on a tool to install $100 in parts.  

Like Bullet, I mounted a modified center punch (converted to rivet buck) in my vise, tucked the window track under my arm and set the rivet with a punch and hammer. You don’t need every special tool that comes along.
All the reproduction top rubber piece that goes at tip of the wing window frame are such garbage they ate not really worth wasting a rivet on.  Agter you close the door a few times, the rubber separates from the metal backing.

Maybe now they make them better???
