Rapom's Rocket - just another Duster build thread

Your column tube should match 72bluNblu's and mine. I would think 2" would be safe if you want to cut the jacket back on your column, but, I don't think you would have to cut the column jacket at all for header clearance. I have TTI's on a 360, blu has TTI's (IIRC) on a 340 which clear the rear header tube with out issue. The tightest clearance point is usually the coupler area. This is a pic of mine with the bearing mod completed with the firewall plate installed.

I actually have Doug's headers on my 340, but it's not a big difference there. You can cut the column jacket back if you want, but it really doesn't buy much space and the clearance isn't needed there. The coupler is the closest to hitting the headers, although even the vibration damped coupler I used is plenty clear.
