Let's have a look at that..

It's a 1G, but I can't parse that Motorcraft number..
E1BE-BA doesn't return any results.
What do you need to know about it?

Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.

This alternator on Rock Auto crosses to your E1BF-BA number.....

Im looking to replace the belt to the alternator but different belts are listed for different amps of alternators. However, if this isn’t an OEM alternator then I’m not sure what belt to get.

It IS an OEM alternator, that's why I show all the Ford engineering numbers it crosses to.

The 70 before the Ford number suggests it's a 70-100A alternator with plug instead of stud for the regulator wire.

Do you have AC?

Gates 70-100A W/O AC #7417
Gates 70-100A W AC #7430

According to RA..... 🙄
These numbers can easily be cross referenced to other manufacturers.

Glad I can help.

Sorry I misread your F as an E at first.... I'm working from a phone.
