sliding door track

A home owner from pembroke ma says:
Hi, I have an aluminum sliding door track that totally have been damaged. I'm looking into repairing the track.

I'm having hard time to figure out the right hight of the track, because this door is a heavy duty and very old.

The track itself is pretty damaged. It looks like it might have been a 1/4" track but the whole door itself can be pushed up a good inch. Because of this would we be better off going with the 9/16" track? Also, the wheels we have are pretty new. Will they work with any new track that we get? The track length is 6'.

Thank you for all your help!

Please take a look at the 80-100 8' Sliding Door Track Cover, Large. The rollers should work with either track cover.
