Getting bolts for my subframe, etc to use?

Can someone please tell me what bolts to use and where to buy them for my 22 roadster rebuild? I am about to mount the wood subframe rail to the metal chassis, but can’t find what size bolts to use for mating them up. Neither Snyders of Langs has seems to have them. Can someone just tell me size and length? Second, are there supposed to be shims between the metal frame bracket and the wood subframe rail? And, do I paint the wood subframe and what color? This would be a big boost to my project. thanks

You may want, if I understand the question, to review Lang’s listing. Model T Body - Brackets & Bolts - Page 1 of 2

Spoke with both and they both say there was too much variance. Ive gone through that listing and don’t see them…What part number are you looking at? That’s why I’m asking what (actual bolt size) you use
