like everyone else said, dremel the rivets til u can get a flat head screwdriver to unscrew it. and no u dont have to replace the entire tb if the tps is messed up. get a replacement tps from another tb, (honda doesnt sell the tps by itself) go get some replacement screws, and u have to calibrate the new tps with a multimeter. .5v closed, 4.5v wot. i would know because i had to replace my tps last year and calibrate and it works like factory.
