The last one is for 1970 W30. Di you own due diligence since I am only showing the listing. I have no idea if it is legit on not.
1970 Oldsmobile 442 Hardtop W-30 for sale on BaT Auctions - ending November 4 (Lot #89,615) | Bring a Trailer

 

That last one is interesting. It would be much better if it had a broadcast card. I think it can fly on the OW trans being original, but that's hanging by a rivet (literally).

 

That 72 has a lot of issues.
