Don't know if it's close enough but Roy Lumber in Bessemer could probably get that for you.
I'll check that thanks.
check any local small time milling operations. Check Craigslist also.
thickness needs to be around 2" or better.
Wouldn't it need to be dried with a special process? If so do most local mills keep the dried product? This is my first rodeo with slabs other than crappie and concrete slabs.
