mirror doors bottom tracks

A quick learner from USA says:

I need two 58 5/8 inches long bottom tracks for four mirrored sliding doors.
These 1 1/16 inches thick doors have concave rollers 11/32 inches thick.
See attached pictures.

I have the two top guides that are similar to 23-245 in gold
( 2 7/8 vs 3 1/8; 1 3/8 vs 1 1/2; 2 vs 1 3/4 inches ).

Unfortunately, i do not have any remnants of the old bottom tracks.
So i wonder whether you have experience in matching such top racks
to bottom tracks for circa 1975 west coast construction ?

As an aside is it typical to install track before or after laying carpet ?
Another related issue is clearance on the total height.

Thank you,

Hello, Scott. Having carpet myself, I prefer the 23-256 or 23-257 tracks. It raises the doors just above the carpet. I would install the track to the solid floor and bring the carpet to the track.
