Ply Gem sliding glass door rollers

Question

I bought a house and the owner told me my doorwall has a lifetime warranty.  But since there are no identification numbers they will not help me. The attached photos show the rollers i need to replace. Any assistance anyone can provide would be greatly appreciated.

Thanks for posting. These old 'tank tread' rollers are no longer made. However, we've had people successfully use the 81-279 as a replacement. The adjustment screw sits a little higher than on your old roller, but the wheel runs nicer than the noisy treads. Let us know what you think.
