https://www.ebay.com/itm/285357571733 Rare 1970 Buick GS Stage 1. All original numbers matching car. Not restored. Still runs and drives. Have Protect-O-Plate, Original owners manuals and brochure. Original paint, drivetrain, Interior (except seat covers) and original wheels. Matching numbers standard bore engine. My father purchased this car new, one family car. No hidden damage or bodywork. No cracks in dashboard, interior in very good condition. Floors have no rust. Trunk has surface rust and pitting but no holes due to rear window seal leak. Quarters have small rust spots at very bottom but easily fixable. I have new air cleaner decals and new foam for ram air intake. Only 2,465 of these were made and fewer in this color combination. Car is located in California. Clean title and current registration
I thought I read that big block cars got discs automatically but yes have seen a few 455 cars with drums
Correct. Disc brakes became standard on the big block GS in ‘71. Small block cars still came standard with drum brakes.
About half of the 1970 455 cars built had power drum brakes, about 1200 more were non-power drum brakes.
The door panels and dash don't look black to me and the front seats compared to the back side of them look different. Almost like blotchy dark brown shoe polish.
