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.
