hood hinges and splash shields

i got frustrated and quit on my 70 duster tonight. figured id ask, someone has to know...

i cant find my hardware for my inner fender splast shields. i remember that they were something like a #10 sheetmetal screw with a really big washer. anyone know for sure, and what i can use to attach them?

also, im finally putting hood springs back in the car. its got an AAR nolt on hood, and i cut the factory springs off years ago. i saw in tony fields thread about him using late model daytona hood springs. so i got some, looked at his picture, and put them in.

they dont hold the hood up. feels like theres no sprong tension. when i put them in, i had to compress them about 1/4 turn to get them to line up and go together. they look just like his picture. what did i do wrong? they held up the steel hood down at pull-a-part just fine.

thanks
