I have a house from 1996 that has an older delta shower valve with a single handle cartridge that has the oring inserts spaced farther apart. My new T17T delta cartridge from the shower trim kit I just bought doesn't fit because it is more narrow with the left and right oring inserts. It looks like you can just pop off the outter shell and in theory get one that would fit the wider spacing. Anyone know if this exists?
