Rivets for my 45 sidecar

[Sidehacker]

Does anyone have the part number or a company who sells the same type rivet that's in the sidecar body. I have totally redone the body, rust and everything not correct has been fixed Replaced the bottom and both sides. The best I can see is the heads are about 5/8s of an inch head, etc etc but would just like the correct rivet to make job complete. This is for a 1945 UL side car

1/4x5/8 thrust head, Old Dude has them I believe or you can try Hanson Rivet and Supply Company, Pacoima California. But they sell by the pound.
Hope this helps. Good Luck
