Looking to replace the cap on my 22" Radiator/383/727 and see there are 2 types for sale. Which is the correct one?

The small rivet x 16 psi Roger. Richard O'Shields has them, but we haven't heard from him in 3 months now. Jamie at Mega Parts is selling it as well..

64-69 is the rivet and 70-74 is the button style rivet. @dadsbee is correct Mega Parts has them. https://www.megapartsusa.com/search.php
