Install radiator hardware?

[AnthonyG]

Hi all, putting radiator back in my ‘35 after over a year, long story & won’t go into. Can’t remember & didn’t take detailed enough pics of hardware. With regard to the spring mount bolts, do springs go above mounting holes or below? Also is fender to radiator hardware flat head or round head screws. Thinking mine were round head as it’s what’s in the radiator hardware zip lock but looks like flat heads might b better?
