396 Cutlass Supremes built with the M20 4-speed. Info from the GM Heritage Center.

How many convertibles with that config.?

Thanks guys. Put about 100 miles on it this weekend. All i can say is wow. This lady really took care of this car. I'll get some doc pics up soon. The protectoplate is about a 3" square plastic card. Different than Chevy cars. Anyone know where the build sheet would likely be? I hate to start dismantling this thing for no reason. :) Spent the weekend cleaning paste wax from emblems / etc. She did tell me when she bought the car she wanted a 442 convertible and her husband said that was to much power. She said she replied "bullshit. " Too funny.

more pics

The last w-30 I owned, I found one under the back seat bottom, and another one in the pass seat upper back. Really nice car btw.

Wow, what a great car, thanks for sharing:)

She does not look happy in that picture! ;)

Really nice car, congratulations!

Super cool car! My dads 70 sx supreme convert had the remains of a BS under the back seat bottom.

Nice Car...is that a cortez silver or what is the paint color name....saw a tint of green in it, maybe just the photo.....

ED, it is silver, title says gray. I need to decode the trim tag and post it. The Boss: She just got done mowing 4 acres. :) Busy lady for her age. She told me noone changed the oil in that car but her. One of a kind lady for sure. Hard working to say the least. Appreciate all the comments. I am finding that buildsheet when I get home. Dont need it, but want it. :)
