Working on a 1950 Chevy 3100 and would like to know the sizes of the bolts that the Factory Assembly Manual indicates. I have three numbers: 122017, 122007 and 120229 . These numbers are associated with the front end panels assembly, i.e., inner fender well, fender brackets etc. Would love to have a "cheat sheet" so I could eliminate the head scratching and cussing
. Any help appreciated . Thanks
