I had planned on doing that for the motor on the Monte, but prices went stupid on the ZL1's so decided to stay with the SBCI actually got mine for about $50 front and back. I bought a wrecked GTO with no drivetrain, took the seats, and sold the rest of the car for $50 less than I paid for it. 😁
I see the seats going anywhere from $200-$500 depending on condition when I was looking.
