RDW: your PM mailbox is full, i COULD NOT REPLY, SO HERE IS MY ANSWER AND MAYBE IT WILL HELP OUT ANYONE ELSE IN california!
yes, I went through my records and it looks like they used a Walker #81712. I had Wally at "Wally's World of Mufflers & Air Conditioning" ( yup, that's the name ) in El Cajon put it on. Came to almost $350 back in 2014. His # is 619-444-1140... if he is still around? Hope that helps
