eBay....I googled it and many sources came up. What am I missing?

I see the issue. When I Googled it nearly all the returns were 205/75x14. I use the 75 aspect ratio on my 53. Is there a necessity for the 70 or could you use a 75? It would only make maybe a 1-2 MPH difference on your speedometer. If you do buy 205/75 make sure they're not trailer tires. That is a very common trailer tire size that nearly all tire shops stock.

I was able to find the size on TireRack.com.  The BFGoodrich had raised white letters but none of them had whitewalls.  I know that I had an issue finding raised white letter tires to fit my 87 Monte Carlo a few years back.  They where all several dollars more than the identical black wall tire.  Tires have gone way up in price.

The 205/70R14 tire is the direct size compared to the 185/75R14 tire.  The tire profiles looks exactly alike the only difference is the width.  Also has to fit on a 65 nova.  Clearance on front fenders is critical.

@1931-roadster You might check with Diamondback tires. I've read they do some custom work but take your heart medicine before you hear the price if they can make you one. A quick look at their site shows they offer wide whites in that size. Give them a call. They brag about shaving tires. Maybe they can shave a wide white to make a narrow?????

195/75-14 Hankook Kinergy ST on a 63 Chevy II. Very pleased, no issues
