The regulator teeth are mostly gone in one area, and I think it is actually seized, so it is what it is.
I've welded teeth back onto the regulator. Then file, dremel & fine tune. Trick is you need to quench it to harden.
There is a complete 66 riv at the local scrapyard. I can check if it has power windows. I can't promise i'll get there anytime soon though.
John. Hope ya catch a luckey break on these. I'm sure there very hard to find. If all else fails I'm sure you may have some luck in the Parts Wanted section.
Are you on the aaca forums, John? If not, join up there and place a parts wanted ad. There's a section just for Rivieras and it's all those guys are into for the most part. Be the best place to find stock parts, I'd imagine.
Couple possibilities out west. https://portland.craigslist.org/mlt/pts/d/troutdale-parting-out-66-riviera/7090898360.html https://portland.craigslist.org/clc/pts/d/sandy-buick-riviera-parts/7075625042.html
Thank you guys, I have a lead on one from the board right now, one 45 minutes from home at a pick and pull, and a third up in NH from the board. Thanks to all those guys so far, lets hope it pans out.
I stopped at the junkyard with the 66 riv today. I needed a wiper arm for the jetstar. The riv has manual windows.
