In the meantime, I had bought a set of OG Appliance wire wheels (ebay)... these were a dealer option and common upgrade in the 70's for a lot of Datsuns - and in the photo on the auction, they were pictured on a 240Z.
Auction description even stated they were used on a classic Z, so, 4x114.3 (4x4.5") bolt pattern.
I spent a whole day detailing them out, cleaning off the accumulation of dust and funk (seller said they were in storage for 20+ years)... Becky takes the Roadster wheels and tires up to our tire shop, gets them swapped out...

She likes them, and I think they'll look great once we have the car repainted (classic Z green, a little lighter than British Racing Green)... with the tan interior and roll bar, should look way cool.
...until I try to mount them. DAMMIT.
Somehow, they're 4x120mm (4x4.72") bolt pattern. No way, no how, are these ever gonna fit on a 4x114.3.
I either got scammed, or the owner of the Z got them mixed up with some other wheels - Or, he had them bolted on precariously without the proper lugs (but it would hop around like a toad on crack).
So, I go to look around to see if I can sell them online... Someone will want them, right?
To make matters worse, NOTHING has a 4x120 bolt pattern (except a first-gen Civic and possibly a first-gen RX7)... neither of which give a damn about chrome wire wheels.
<sigh> DO. NOT. LIKE.
