Vehicle Emission Control label?

[H-K]

The VEC (underhood sticker with engine/emission specs and routing) is missing form my donor vehicle (along with all the smog equipment) and although some of the info is available in the Chilton's manual, the diagrams are tiny, grainy, and unreadable for the most part. I've tried searching around on the net a bit, but have hit a bunch of dead ends. If anybody out there with a ~1991 Chev/GMC pickup 350cid AT could snap me a digital pic, I'd be extremely grateful and will keep you in mind when I win the lottery.

If anyone could point me in the right direction as to where else I might find this info, I'd also be grateful.

Thanks!

I don't know if it's any different, but I have a '94 GMC 350/AT. LMK if you need me to get a pic.

Thanks. I think the throttle body on that year had a different provision for vacuum routing, but it might still help me understand the general component layout. I don't think the pickups had Vortec heads until '96, so I think yours has the same swirl-port heads as mine and mechanically, I think they are the same, but I don't know for sure. I'm also unsure if there were any emissions regulations that were changed between '91 and '94 that would necessitate a modification to the emissions system.

Thanks for the offer. Hopefully somebody out there has a '91 that can help me out. I'll let you know if I need the pic.
