the website was swedish, so I couldn't read all the info, but I could make out G and 1986.

So can someone help with more accurate identification and also if it crosses years, as in 81-86 etc.

The G-body is the 1981-1988 GM midsize RWD cars (Cutlass, Monte Carlo, Grand Prix, Regal, Malibu, El Camino). The 78-80 cars are identical, but are technically A-body cars. Some of these G-body cars, mainly diesel cars and the tubro Buicks, used hydraulic brake boosters that are even smaller. There are two flavors of hydraulic boosters, the hydroboost, which uses the power steering pump and fluid, and the Powermaster, which uses a self-contained motor to pressurize brake fluid as the booster fluid. Hydroboost boosters can be found on pretty much any one-ton Chevy pickup.
I plan on putting a swinging pedal in my '55 and this setup looks much simpler than what I was working on.

thanks
