American Racing used to make a very similar set a long time ago. They also look like an older model of Jongbloed wheels. They've been around for quite a while.

Not many left, as you've discovered. Only other car I can think of that had them as an OE size is the early C4. Falken makes a 255/50/16 but they're pretty much hockey pucks. Price is right though.
The 16" cross lace wheels could be had on T/A's and GTA's.
T roof on a 5.7 was possible until the end of the '89 model year, with a few exceptions.
4 wheel discs make it a T/A or GTA.
Highest gear available with auto was a 3.27 in the 9 bolt. 3.42 and 3.45(9 bolt) only came with G92 equipped...
Lebron would be able to hang with Jordan for about 2.5 quarters and then Jordan would step on his throat. Lebron isn't wired properly for what he needs to do to be considered one of the best ever. That's why he signed with DWade. Wade is wired to finish big games.
I enjoy watching Lebron play...
One of my favorite wheels with one of my all-time favorite tires. You sure you won't ship? You could UPS them and they just staple a waybill right to the tire. Most people tape a cardboard disc over the pretty side too.
