Supra seats fit pretty well with almost no/slight modifications.
For ease of installing the main thing for our trucks is to find a seat that's lowest point on the bottom of the seat are the seat rails. (You don't want the seat hanging lower than the seat rails.) It just makes it easier to make simple brackets and install.
1st set of seats were out of a sami zuk. Flat bottomed seats. Easy to mount.

2nd set, prelude has bubble butt, and required making drop down brackets so it didn't drag on the floor pan so I could move the seat forward and back if needed.
