Gary, keep up the good work. Don't be deterred by my evil-eye observations. The tendency is to become fascinated by all the minutiae involved with these cars.
Yes, figure 13-407 applies to your car. In fact everything in the last 60+ pages of that chapter concerns your Automatic Climate Control system.
Presumably the guy on eBay with Briz Co Inc, itsjustbriz@aol.com is the source for the repro faceplates. He has built quite a cottage industry selling these for various model years of Buicks. One idea is to find out if he has plans to produce the plates for the automatic system.
He uses a place that makes vehicle wraps to create the A/C faceplates. It would be interesting to see if a print shop or wrap supplier could make these out of thin plastic? The setup charge could be prohibitive though. I believe I could make a crude version using a laser printer and some leftover transparency stock intended for use on the old overhead projectors. Graphics from the shop manual would be used to create a layout of the master image. A coat of black paint would applied on the back except around the lettering to minimize light bleed-through. Then a final coat of white on the back to make letters illuminate correctly from the dash lighting.
Given the hints in the other post on using the online master parts books it is now possible to directly research the '70 Riviera dash pad. Also it now is possible to ID the A/C control unit and faceplate part numbers on the slim chance one of those will show up for sale somewhere.
