Just for shots and giggles, measure the distance between 3 rivets on the old chain and divide by 2.
You think maybe the old chain is .404?
Could be?
old chain
new chain.
Can you send the new chain back?Might be worth it to take the saw with the bar on it to a saw shop & have them cut a loop to fit.
Saw is gone. Was the guys first mcculloch and his last name is...... ..... Mcculloch. His Mrs calls him Maca. Guess it's gone to a good home and will have a nice life
Re the chain I'd probably just take it to the shop too. They will sort it
I believe a 28" D176 would typically take 92 drive links anyway.
so, could the old chain have stretched this much?
In my experience I've never seen a chain stretch that much.One or two DL at most,but never four .
Are you sure the original chain is an Oregon?What are the #s on the DLs?
May just be my eyes, but some of the tie straps appear to be longer than others.

so, when you look at these photos, the old chain (top pic) fit the saw fine. do you think getting a chain with 3 more down links (going from 89 to 92) would be enough?
The bar is what you need to be analyzing, not the chain. A typical 28" D176 calls for 92 drive links of 3/8 chain. If you don't have a local shop that has another D176 for comparison, call Frawley's Saw Shop to get it sorted out. The profile of your bar looks a little wider than a more modern D176 with that number primarily referring to the bar mount characteristics and not necessarily the overall bar profile. That said, 92 drive links are what's called for on a modern 28" 3/8 .050 D176 Oregon product. But don't take my word for it...

coincidentally Frawley's is where I ordered the new chain from. I'll give them a call.
spoke to Jim Frawley an hour ago. he said it was quite likely that as the chain stretched over the years the old farmer (his words 
probably had a link removed now and again and it went from 92 to 88 links. he is sending me a 92-link chain and I will return the new 89 link one to him.
he said he was a salesman for McCulloch back in the day.

oh, he also said going from .050 to .058 on this old worn bar was a good idea and was commonly done in the days when people were careful with their money.
The noticeable difference in drive link wear between the two chains probably accounts as much for the difference in fit on that bar as the stretching.
Glad you got it sorted out.
