Gleaner F Serial Number and Carb

Getting sick of using my All-Crop 66 and 90. We only do a small amount of grain - only what's required for our cattle: At most 25 acres a year. The 90 is beyond worn out, and the 66 canvases are a real pain with the hay we underseed sending a lot of green material in with the grain and not travelling up the canvases well. Rightly or wrongly, last night I bought a Gleaner F with the 292 at an online auction for $390. Not sure it was a wise move. I only looked at it once briefly in the dark. It seemed ok, stone door and raddle looked good, no rusted out elevator or bin bottoms, seems to have always been stored inside. The main catch: It hasn't ran in 20 years. Which doesn't concern me too much: I have a spare 292 kicking around, and oodles of parts for every Chevy I6 of that era.

Rightly or wrongly, I'd like to drive it home. It's about 60 miles from our farm (which is about as close as I could hope for, as we're not in a farming area). Prices I've got for floating it are over 5X what I've paid for it. I'm going to head out to the auctions site this weekend to pop the carb, fuel pump, and fuel tank off. I'll bring them home, clean them up, and put kits in the carb and fuel pump. I'll then come back with them, a battery, and a pile of fluids and see what happens.

If I can get it running and it seems to be working ok (which I realize is a big 'if'), my only other concern before driving it down the road would be the main and traction drive belts. All belts looked pretty good when I did my hasty look at it, but just in case I'd like to order a set pre-emptively to have on hand. The AGCO parts website lists two sizes of belts, depending on serial number (and the serial number break for the belts is later than the serial number break when they switched from the Buda to the GM engine, so I can't go by that). I asked a guy at the site to see if he could see any markings on the belts, but he couldn't find any. When I go there this weekend, I can do my best to measure them and match them to the appropriate belt-size accordingly. But I'd really like to know the original/stock size.

This is a long-winded way of asking: Where is the serial number located on these combines? I don't want to be searching around it for hours on the weekend trying to find the tag. I'm not planning to order the belts from AGCO (I can get quality Kevlar V-belts from work much cheaper). But if I can find the serial number, I can figure out the AGCO part number for the belts and cross-reference them to their standard V-belt size.

Second question: If anyone happens to know what carb was on these, it would also help me. I'll be able to find out this weekend, but if I knew now I'd get a carb kit on order now, just so it would arrive a few days sooner. It's definitely not the Rochester carb that GM used on the 292 in their cars/trucks. Judging by pictures of the AGCO carb kit (which is ridiculously priced and long-lead at AGCO) I'm almost certain it's a Zenith 28. But if anyone knows for sure, it would be greatly appreciated.

I don't remember off the top of my head where the SN tag is on an F (I have mostly focused on As/Cs) but I thought it was on the LH side like the As/Cs. If not, it is at least in a fairly obvious spot on the outside of the combine.

I have a set of the main drive belts on order, but not the traction belt. The traction belt is not a standard V-belt (it has the width of an a E-belt, but the height and cog profile of a DX). I'm hoping the existing one will at least last me until I get home, so I can do some more evaluation of the whole thing before I spend almost as much on the Agco-specific belt as I did on the whole combine.
