How To A-833 4 Speed Rebuild pics

Just in the middle of painting mine and putting it back together...I have 1 oddball bolt for the side cover. I dont think its correct...I think the previous owner used what he had. Notice the shoulder is longer and the bolt itself is longer?? I tried in all the holes and doesnt want to snug up. I dont want to "stack" washers either. Any ideas??

Thanks
