Other than the fact that you cut the top hump down is this the look you're going for? If I do shave my firewall I'm going all the way with this look including relocating the booster to the frame or under the dash....so it'll cost me about 2G to do between Vintage air and the frame mounted booster setup and pulleys for the A/C, etc....
But it looks SOOOOOOO sweet!!!! (Especially with the LSX like in this picture)
