I have 2002 Chevy Silverado seats in my 57 TF, but getting ready to go back to stock. The seats fit great with only 4 holes required. I also like that the seat belts are integrated in the seat. Very comfortable....The only reason I am swapping is that I am 6'4" and the seats are thick so I am a little crowded. I also could not fit in the small center seat, just the buckets.
