Modern seats to 79 Trans Am

Lexus IS 300 power leather bucket seats measure measure 21" wide, 24" long and 39" tall with headrests and the runners seem run something like 17 wide and 17.5 long. The trans am seats run about the same except the runners are different and it's 31 in tall. I'm figuring on some cutting and welding for the runners. I have two questions. First how hard would it be to wire up the power seats to my 79 Trans Am? Two how hard is it to modify runners, being that they are power? Should I just change up the runners or attack the floor pan? I've never done a seat swap like this before.

I am going to put your question into the electrical section also. Basically, the motors that run your seats are forward or back, up and down based on polarity, so it's not hard to wire them into your car. You may need any plug that was part of the wiring harness attached to the Lexus seats. I keep a charged up 12 volt battery with two long leads attached if I need to move seat motors in seats that come in without the car.
The seats just have to sit level on the floor, so you either need to shim the Lexus brackets, or fabricate mounting brackets to attach to your Trans Am's floorboards. Either of these procedures is just trial and error.

No one lives forever, the trick is creating something that will.
