No thanks...I've got a copy of the GM EPC; I'm just always on the look out for an updated version.

What version of AllData are you running? I had a copy of AllData before I snagged the EPC...I can see from your post that the image quality of their diagrams has improved dramatically. The version I had was older and many of the pictures looked almost hand-drawn.

Here's the same diagram from the EPC, they're almost identical:

Electronic Parts Catalog

It's the Snap-On/Proview software that GM dealers use in their Parts Departments.

That's a good question. I believe there's an initial cost AND a yearly fee.

That said...I'm fairly certain that only an authorized GM dealer can purchase the software. I found a copy on the Internet a while back and pulled it down...not the most 'legal' of acquisitions, but neither was half of my mp3 collection.

I used a slide hammer to get mine out. However keep in mind if you break that retainer spring you need to split the case to get the broken pieces out. I broke the one on the long shaft when installing my front locker.
