WTB: 68 Barracuda Bolts etc

I know it seems easy but my head is spinning trying to find these so...I'd like to buy from someone new/used fastners for my front end. i only have a couple of them...

pretty much all the fastners that make up the front end going back together.

if you have sources that would be okay to. i'm just not sure what size bolts and to buy...

thanks,
Junior
