I go to the junk yard with an empty coffee can, and get OEM Mopar bolts from trucks and K platform cars.
They usually charge $5 for a full can.
In fact, that's the reason I can't bring myself to scrap either of may parts cars, At up to $5 for two or three bolts at Lowes (or MUCH more from the places listed above), I can't afford to get $50 for the hulk and throw away $200 in bolts and fasteners.
