I want to put the drawbar back on the A, but I don't have bolts. Is it 4 bolts, all the same size? What size are they? I found them online, but they are $6.50 each, and it doesn't specfy if I need 4 of the same size and length.
 
Not at home so can't answer size but bigger square head bolts on the back maybe 5/8ths and smaller maybe 3/8ths in front. If you don't get a better answer I will measure tomorrow.

My answer may not help you. I have Super As. The bolts that attach the drawbar to the final drives have hex heads which are tapered and lock into the drawbar. My bolts are all the same length.
 
Go to your local hardware store. Lots cheaper than dealer.Not if you just HAVE to have square heads. IH for those, but they will most likely be Obsolete/No longer available.
 

I have 4 of these bolts if you're interested. 5/8-11 thread... very good condition. $5.00 + small flat rate USPS SHIPPING

treeman, I measured the drawbar bolts on my BN's which should be the same as your A.
Here is what I find.
The rear bolts for the rear drawbar are 5/8" X 3 1/4"(3" would be ok). These are square head bolts as the heads lock into the final drive castings so they don't spin while being tightened. The book shows them as fine thread but all of mine are coarse thread. They have hex nuts with lockwashers under them. Nuts are towards the center of the tractor.
The front bolts for the rear drawbar are 1/2" X 1 1/2" coarse thread with lockwashers under the heads.
The rear drawbar can be mounted with the mounting flanges up or down to change the draft height. Usually the mounting flanges are up which puts the drawbar at it's lowest.
The bolts for the front drawbar are 5/8" X 3" square head with hex nuts and lock washers.
I suspect these all should be grade 8 bolts but I don't know that for sure. I can find square head bolts at Menards but not sure of size's or grade.

I checked the Parts Manual, and it shows 5/8" x 3" NF bolts and nuts for the rear of the drawbar, and 1/2" x 1-1/2" NC bolts for the front of the drawbar (where the adjustment holes are).
