Replacement Wheels

A home owner from Atlanta says:
I have a large sliding glass door on my house built in 1957.
I'm unable to find a roller assembly that looks close.
Can I use 81-272 to retrofit?
The existing 1 1/2" nylon wheels are not concave.
I assume I can drill out the existing rivets holding the old wheels and use the included axles. My main concern is with the concave wheel mismatch. Do you have non-concave? Does it really matter?

Dave Sr. from SWISCO responded:
Thanks for posting. Looking at the wheel in your photos, it appears that could have been concave with one side having worn down. Could you confirm? If so, see our 81-236 wheel with the 81-310 axle kit. That may work. If not, is there any way to see the housing out of the door? That may help us find something better.
