Harv, The cylinders were a little on the large side. When I ordered them from Northern hydralics, I ordered 2 1/2" cylinders expecting that to be the outside diameter, but it turned out to be I.D instead. Oversight. Oh well, After what I went through to get them, (4 weeks), I didn't want to wait any longer. So I used them. Lift capacity is probably more than the tractor can handle. I try not to over do it. I am confident in the welds but fear of breaking the tractor itself. Thanks for the reply.
