If any one is looking for a build sheet and has not checked the upper portion of the back seat maybe you should take a look. I picked up a rear seat from a member here that was from a 72 Skylark or GS and the remnants of the build tag weere attached to hog rings on the upper part of the rear seat. The tag was attached to the lower right part of the upper seat near where the large washer screw attaches. Not sure what the car was but it had a code red 75 code and A white top. Also engine code "PB" and a few other things. After removing my 71 Stage-1 seat ramnants of tag were in the exact place. Unfortunately very little of my tag has survived.
