70 Nova Front End Hardware

[mr.nova]

Can anyone recommend a good place to get the front end sheetmetal hardware (bolts,clips. shims,etc.) for my 70 Nova? Do you think Chevrolet still sells these or am I out of luck with that thought?I'm thinking I'm out of luck!Anyway I always seems to be an impossible task at the dealer for small things like this on an old car,they don't want to be bothered.This is why I thought I would ask the experts. I will need for the fenders,rad. support,bumper brkts,etc.Looking to get a good quality.I can not seem to find all the hardware I took off some years back. Some of what I did find are rusted,stripped,or broken clips and I just rather get new. Thanks
