This is a 32" long door bottom from a Johnson double door installed in 1986. There are 5 sweeps with the largest sweep having a depth of 5/8". The door bottom measure 1 5/8" wide and the distance between the kerfs is 1 5/16"

I don't think we have this same door sweep, but our 58-176 may be worth considering. This wraps around the bottom of the door so it's a little more versatile than your sweep, which plugs into two slots. See what you think.
