My advice is dont take that grommet out of the bulkhead, its a bitch to get back in. instead cut the pipes flush with it on the outside to the matrix car be removed from the grommet leaving it in place, then take a Stanley knife and cut the grommet between the pipes

Slit the red line so that the new matrix can be refitted easy
