Ariens snow blower attachment

I just got one of these, 48" 2 stage to mount on one of my Ariens tractors.... though I have to go thru it and totally overhaul it due to it having been in a garage fire... glad to have it because they are so tough to find for this model tractor around here.... I have it narrowed down to being either model number 831009 or 831010. but if it is the 010, I do not know if it is the up to or after serial number.... I know it isn't the 831025 since it don't have the auger clutch.
I have 2 driveways of my own to maintain plus about 4 neighbors that are too old/shouldn't be out there dealing with snow that I have been "drafted" to take care of.....

ANYWAYS does anyone have any parts for one of these laying around? Not concerned about normal consumables, such as bearings/ bushings as those are easy to find.... but I need the 10" pulley that drives the impeller, NOT the cast iron ones with the bearings within... this is a stamped steel one that is tack welded to its hub, closest to the backside of the housing on the main shaft.
Also looking for info on common (SKF, National etc brand) part numbers on the gearcase seals because I am trying to avoid going through Ariens for parts as much as possible because they are nuts on their prices.

1 more question. I was looking on FeeBay, and saw a gear for an older Ariens walk behind for the bottom of the chute to control the rotation. I am wanting to adapt a different setup to this blower for that function vs the drum and cable setup that it came with. Does anyone here know what model(s)of snow blower would have a gear like this that would fit this machine? Or if the taller chute from a newer Ariens walk behind would interchange with my machine? I have a power window motor here that I think might work, out off of one of my old trucks, to rotate the chute.

hopefully someone here knows something about these. I have mine all 100% apart and the bigger pieces headed for the sandblaster to be powdercoated. Too cold for paint right now and I need this thing functional.
Nother question... what is Ariens Lubricant #2? That is what they want in the auger gearcase

Arrrgh...no replies. Aggravating. Got another question that I hope someone can answer
What is ariens L3 lube??? Something else that's more readily available that I can use instead ????

Stupid on screen keyboard someone spilled pop on the regular keyword can someone else clean up the duplicate posts??? Thanks

Hi Don there are not that many Ariens machine around but I did a Google search and it seems the L2 lube has been replaced with L3 (Ariens numbers) and from what I read its a synthetic gear lube but Ariens says not to use just any Auto Gear lube found another post that says Mobil Delvac Synthetic gear oil 75W-90 80W-140 is ok (no guarantee just some information)

well got it going, works great on my GT19 with its power steering as opposed to the S16H with its Armstrong steering, I never thought I would be saying that.... probably the vehicle I miss the most from my past, was a 79 Dodge 1/2 ton with manual steering.... along with manual brakes and 3 on the tree,
I'm just afraid to tally up what I spent rebuilding this snow blower attachment
