Defroster vent replacement - How hard???

I added the dual exhaust about 15 years ago. Mine was an export car to Canada and strange thing is that it never had a converter on the single. My grandmother never replaced/touched the original exhaust (except for the odd muffler) so it escaped the emissions police. If I bought the car used I would think the original owner removed it but having the service records and asking my grandmother about it before she passed away confirms that it didn't have it.

Also decoding the fender tag told me that the car was built on Valentines Day in 1975 which happened to fall on Friday that year. I didn't think much of it until I took the interior apart last Fall for the restoration. Odd nuts and bolts were used here and there in the interior and the best part was noticing that the two clips that hold the package tray on were never installed when I removed the tray. After I removed the carpet the next day I found the two clips in the back seat foot well area. I suspect the assembly line workers were thinking about what sort of action they would get later that night... perhaps that was why the cat was never installed?


The front seat in those pictures look like buckets but they're a bench with fold down arm rest. Here are a few pics when I cleaned them earlier this spring. My grandmother had seat covers on them for 15+ years so the cloth looks like new.



The colour is Cinnamon metallic with the same parchment/champange top you've got on yours.
Here's a thread to a few pics of it w/o the vinyl top installed yet.
