Alternator Bolt Size

[BradMugs]

Searched the forum but can't find what I'm looking for. My son and his friends decided to get my beloved truck fixed up - not sure why it runs great for me. Anyway yesterday after adjusting the alternator two of the three bolts fell out while they were driving around. So, I need to fix it and I don't have the time to mess around. Can anyone give me the sizes of what I believe are three bolts (and nuts if needed) so I can make one trip to the store, get it fixed and the boys out of my hair (what's left of it).

Thanks

If it helps it's a 1980 truck. I could really use an answer here....

Well, as no one seems to know I'll let you know what I ended up doing to maybe help the next person or just keep a record for the next time this happens.

I purchased two 8mm 1.25 thread 25 mm long bolts from Home Depot. These will work for the bottom front hinge and the swing arm (didn't need it but thought I'd replace it while I had everything apart. For the back bottom hinge I got the same bolt but 30 mm long with the proper nut. the only bolt I didn't replace was the long one that holds the swing arm to the engine.

Hope this helps someone else save some time.
