Is anybody who is using an SAH adaptor for a twin choke carb able to tell me what the thread size/pitch is for the 4 studs?

Am fitting one to #1 daughter's car but it came without nuts, and I can't find anything that fits it - not even from my fairly large pile of old V4 spares. Thanks!

My adaptor has 5/16" UNF threads both sides of stud. Stud length overall 40mm. With 8mm thread at adaptor end and 20mm thread other end. I did use 4 flat washers + a Thackeray washer under a nylon nut.
