I will try to find the info on the Las Vegas store with the bearings, races, seals, and washers later tonight.
My next step was to get some kind of cover. I knew that the m416 is very close to the canadian m101. I saw old used canvas tarps for the m416 on ebay and then I saw that you could buy NOS vinyl tarps for the m101. The new vinyl tarps were only a few bucks more and since I wasn't doing a historical resto, I sprung for the vinyl tarps and hoped that the loops would match up to the loops on the trailer. I thing I paid about 80 bucks for the tarp on ebay. Last time I looked they were still selling them but I am nut sure if it was the same seller I used or not.
I received the tarp and it was NOS just like stated, it was still sealed in the original bag. It is a super thick vinyl with reinforcement for the corners, it also has a really nice rubber bungy like cord that is used to hold it on the loops on the trailer. I fits perfectly and works wonderfully. I looked through my pics and I don't have any good detailed pics of the tarp and how it attaches. I will go take some now.
Pics:
Sorry, it is kind of dirty right now
closeup of how it hooks on the trailer
closeup of how it attaches at the back and how you can adjust them tighter by pulling them through the end hooks farther
And one cool function of the tiedowns on the trailer
perfect bottle opener no matter what side of the trailer you are on.
