So I'm wondering what you all think about the many different brands out there as far as fitment is concerned. The three I am looking at are JBA ST, BBK ST, and Pacesetter LT. I have experience with the BBKs...I bought them and installed them once. They were a bit rough especially this one particular bolt. But not too bad. So if any of you has used either or all of the particular ones I listed, please let me know how difficult/easy it was to install and how the fitment was. I have an 03 GT convertible automatic if that helps. Also, if you have a particular brand you can recommend that will be an easy install then let me know. BTW, the heads will be off the engine but the engine will still be in the car. So that should help. Thanks guys!!
