If you have access to a Hyd. press you can make a riveter out of a 3/4" grade 8 bolt.
Here is a sketch showing you how it fits inside the receiver, so you can squeeze the rivets. It helps to keep the bolt as short as possible. You will need to buy a 4" or 5" or longer bolt so you can cut off the threaded part
I used a cheap angle grinder with a thin cut off wheel to cut and shape the bolt.

Be carefull not to get the bolt too hot when grinding, because that will take the temper out of the steel & you will need to get another bolt to start over.
