If you want the exact rivets used by the factory, I would get 1/8" Brazier head rivets. The designation is AN455A4-xx. The xx is the length in 16ths inch. These are hardened 2117-T4 aluminum, indicated by a small dimple in the center of the head. They are 0.312" diameter, the head height is .062".
If you are replacing existing rivets, I would use 5/32" Modified Brazier head rivets. These are AN456A5-xx They are the same head size as the original Brazier head, but one size larger on the stem diameter. So a 5/32" Mod. Brazier has the same outward appearance as the 1/8" Brazier head rivet. It's kind of like putting oversized valve stems in the old Chevy. Just the act of drilling out the old rivet will enlarge the holes, so you ream the original holes out to 5/32" (actually 0.160"+/-) and put in a Modified Brazier of the next larger size.
Or you can use Universal head rivets of the next larger size. The 5/32" Universal head rivet has the same diameter (.312") as the 1/8" Brazier, or the 5/32 Mod. Brazier, but the head is slightly taller than the Modified or orginal Brazier head. The head is .072" high.
It's a little hard to tell the difference after you get done pounding on them with a rivet set. I used Universal head rivets on my '59.
edit: this applies to vintage trailers. I don't know what they use nowdays.
