I used a 2018 Mustang GT350 VIN to verify it since I didn't see you share any details here. If you'd like to check, go to parts.ford.com and enter your VIN.

Click 'Search Catalog' without entering a keyword or part number. It will ask you for your zipcode to show you prices at local dealers. You can order through this system and pick up locally, if you want. Note that different dealers in this system have different prices, so feel free to shop around if you ever want to utilize it and have multiple local dealers. You pick up at the parts counter like normal and freak out the parts guy who didn't remember placing your order over the phone or in person . The site also has free shipping on most smaller items, which usually comes by FedEx for me in a couple days. Sometimes it works out that their higher price+free shipping works out to be overall less expensive than the lower cost+paid shipping from online retailers for smaller yet heavier items. If the free shipping is an option, take it. It's all coming from centralized warehouses so even if you pick it up at the dealer it won't be arriving any quicker if it's not an item they stock. Zip code is used since any online sale counts as coming through that particular dealer, even if you never visited them, with their particular list prices.
Then use the search at the top of the page and input the above part numbers and the website will confirm the fit.

The Ford website doesn't display the full part numbers, like 'FR3Z', however it will allow the full part numbers as search inputs which allows you to verify the fit of full part numbers from online retailers.
Bringing this one back up. The larger Oetiker clamp on the inboard boot on my drivers side slipped off the axle. Super odd.
has anyone tried the rock auto axles? Since they’re not a safety hazard if they fail the $100 price point might make it worth a shot.
Follow up:
so I did installed the GT 350 axles on which I had to swap the original boots for the gt4’s.
I exploded both inner boots on my second session on track. It was like 40 outside and both sides broke so I highly doubt it is due to heat. My differential is cooled.
I honestly don’t know what to do anymore.

I ended up installing the Ford Performance axles. Been good so far. I also used the grease recommended by G-Force (makers of the axles). I had to change the boot on one side as it was rubbing on the spring.Chuck did you find a solution? Just tore another boot, this time outboard passenger side. Thanks.
