Scrap of cement backer board (Scotts Valley by Vine Hill Rd.)

Does anyone have a scrap of Hardy board or any other brand of cement backer board?
It should be a quarter inch thick and be at least 28 inches long by 4.5 inches wide.

Just checking before I buy a 3 foot by 5 foot sheet of backer board (which would be on Monday,) since I only need a strip that's 4.5 inches wide.

Or possibly if you have a regular size sheet and can spare 4.5 inches off one end... But don't have an angle grinder to cut that off, I can bring my angle grinder to cut it off when I pick up.

If you noticed I'm in the middle of nowhere on Hwy 17... But you happen to be anywhere in the San Jose area, I will be in the San Jose side of things on Monday.

Thanks for reading and considering!
