Couple problems

Hi everyone, Thanks for the ad. I recently bought an old U haul f350 with a 7.3 diesel. Runs great after some normal maintenance done on her. However, I cant keep the alternator and vacuum bolts tight on the thing. I would like to just replace them all but cannot find anywhere that has bolt size specs. Anyone on here have that handy you could share with me ? ALSO, I replaced the headlight bulbs and now it runs low beams on high and nothing on low. Any clues there . Many thanks for any help you can send my way. BTW, I did use bolt locker ( or whatever it is called ) on all of the bolts.

You didn't share what year F350 but I would guess your headlight issues are from using the wrong bulb. You might have bought 9004 and actually need 9007 bulbs. Or U-Haul converted the truck to 9004 and you bought 9007's.
