Looking for external bolts for 1970 A Body for mounting body panels

I had very good luck the first time I posted on the forum so I've come back to throw myself on the mercy of the FABO community.

I made the mistake of getting body work done at the wrong place while trying to save money on the job. I was forced to find another place to do the work while the car was still in primer, and now I've gotten my car back with missing parts. Most important thing I'm missing is bolts for mounting fenders, valances, bumpers, doors, etc. I also need to replace a fender extension as well, the drivers side.

If you have any of these parts, please let me know. My new body guys don't want to start my serious work until they know the car is complete.
