Three lift arms. top one is from an NAA/8n , Bottom one is fits all 100 series including my 541,641,741,960 $ 860 What does the middle one supposed to fit? It came with a bracket to hook the check chains for the 6/800s But the holes are a inch off, especially if one is to use the short stabilizer bars for the row crop. Hope the picture appears. Have a grand son helping.

Turn first one around and see if hole line up???Some have check bracket rivet to them in two holes?? I think Offset have five hole in them.
 
As stated previously, all my 100 series tractors have the center hole in the middle ,16 inches from either end. The 741 , my winter project, had 8N/NAA lift arms on it . I got two lift arms of ebay for it, fitting 5, 6,7,8,900 tractors. those lift arms had the bracket for the 6/800 check chain. .Didn't notice the difference until I tried to put the row crop stabilizers on .they don't fit . Not when the center hole is 15" from one end and 17" from the other. So what are they supposed to fit? Are row crop tractor lift arms different than ag tractors? Always thought they were the same until this. UPS made a bunch of money on this , at my expense
 
"Are row crop tractor lift arms different than ag tractors?"

In my experience, yes, they are different, but I don't know where
the break/differences were. Row crop, x00, x01 or what.

Here's a similar picture of one off an 8N and my blue 960.
I believe both of these to be aftermarket as the 8N arm has squared
edges and the row crop bar does not have a hole for the stabilizer.
The length and the hole spacing is obviously different on these though.
As is the size of the arm and the connecting arm bolt hole.
Wish I could be of more help. I'd be happy to take measurements, etc.

First time I've seen a 100 series with one hole, and it is not in the middle!. On another not. NH's parts site doesn't really give a very clear description as to what part number for what tractor either.
 
I bought a 3000 (a Cat 1) tractor with Cat 2 lift arms per the PO.

In trying to buy new Cat 1 arms for it (so that my Pat's quick hitches don't stick out so far) I found that there are different sizes between 31 and 32.5" (hole to hole centerline) dimensions with the attached 3 hole (riveted) chain attachment bracket. All available seem to have the same angles on the mounting points and have the 3 hole bracket, just different colors and lengths. The other thing is that you need to have the seller physically measures the arm being sold, not just take the part number for granted.....not reliable as I have found as some ads use the words suitable for, replaces, will fit. bla bla.
