the SWSA official tripod uses this thread, if you wanna convert yours to that as standard "Standard 3/8"-16 Mounting Thread"

your link to the tripod didn't work for me her it is in case others were having same issue https://www.amazon.com/dp/B004EIL4R2

you can walk in to a hardware store if not fully confident with it all and ask them to show you the replacement bolt , which depending on the design of that tripod is probably quite easy. generally involve remove the existing 5/8"-11 thread and insert 3/8"-16 in its place. some form of adaptor here is less ideal and doesn't look like that's necessary lookinag at the comments in that listing, there is someone for example who has successfully replaced the bolts and using that very tripod for SWSA
