68 340 Exhaust Manifolds vs TTi Shorty headers

Just a note on TTI shorties. I am putting a set in my 74 Duster (360 with a Tremec TKX) and am making mods to my zbar and clutch fork to get enough room for the DS adapter pipe to fit between the clutch linkage an torsion bar. Had to get a short clutch fork in the hope that it provides needed clearance.
