Good evening! I've spent several hours brainstorming and trying ways to properly install the dash carrier (instrument panel) back into my 69 firebird. There are 4 slots in the dash pad that line up with the top 4 screw holes in the (original) instrument carrier, yet no holes in the sheet metal behind the pad. My guess is there are supposed to be a threaded gromit that installs in the slots, but after hours of searching the net, I am unable to see if this is true or not and/or locate the part. The shop manual is lacking in detail to answer the question and I've checked the FAQs/posts on this site. The prior owner had it off-center and unstably screwed into the pad itself (which appears quite wrong).
If you have a 69 or are aware of the answer, could you help solve this frustration? How is this correctly attached to the dash pad?
