I'll have to scan them for you later. Even at this stage it's worth your while to buy a 72 Cutlass Assembly Manual.

 

OK thanks. Where do you get one?

 

Go on eBay and use 1972 Cutlass Assembly Manual as the keywords. They're not expensive at all. I'd get the hardcopy instead of electronic version, but it's up to you. BTW, none of the Assembly Manuals I've seen appear to have every last detail, but they sure have a lot of good diagrams for things like what you're doing. If you tackle the dash and electrical those diagrams are a Godsend.
