The thing is that the PO replaced a lot of bolts with metric ones. I don't mind an awful lot and I wouldn't spend hundreds of dollars replacing them but if I can find inexpensive bolts to replace them I will. It hurts my eyes to have different bolts in a row. Plus the ones he put on there have very different surface treatment so they really stick out.
And of course all the bolts that go into the engine or frame rails have to be SAE. I have some of them but not all. The fine thread ones are not so easy to find.
65dartcharger has a heck of a lot of bolts (and other stuff) but he refuses to charge me so I can't keep asking him. Makes me feel bad.
