Check with Vintage Air in San Antonio or Old Air Products in Ft> Worth. Both of them actually design and make much of their stuff while most others just box up components from various sources and then sell it as a kit. If no one has a kit for your set up You can PM me and see if you like the home made one I did.
Old Air is what I have. It was a draw between Old Air and Vintage Air. Old Air won out because they have an option that provides a vent that mounts where the old speakers were located. This eliminates the need for that pesky vent run at the bottom of the dash. The install was not too difficult. I live in Dallas and have a 2nd home 30 minutes north of San Antonio so location had no bearing on my choice.
