HEADER FITMENT • Our headers were designed to fit with the engines located to the factory specifications.  If the engine is not located correctly in the chassis, the headers will not fit properly.  We strongly suggest you check your engine location prior to installation.  (Click here for the factory dimensions) • Due to various manufacturing designs, aftermarket parts, engine configurations, suspension combinations, etc... TTi cannot ensure headers and exhaust systems to fit all combinations.  However, we have done our best to accommodate both factory and aftermarket component combinations.  In some cases, slight modification or repositioning may be required on your part to clear the specific situation.

1.  PLATFORM:	67-76 A-BODY, 62-74 B-BODY and 70-74 E-BODY
2.  V8 ENGINES:	5.7L, 6.1L, 6.2L (Hellcat)
3.  CYLINDER HEADS:	OEM
4.  FRONT SUSPENSION:	OEM or EQUIVALENT, RETAINING THE TORSION BARS •  UniSteer Performance Rack and Pinion:  Headers will not clear. •  Firm Feel fast ratio pitman & idler arm:  Headers will not clear.  The Firm Feel arm is 3/4" longer than the stock arm.  (The OEM arm measures 5-1/4" from center to center)
5.  ENGINE MOUNTS:	OUR MODIFIED DESIGN MOTOR MOUNTS/SPOOL MOUNTS ARE REQUIRED, sold separately.  [TTi Motor mounts]
6.  AUTO TRANS:	904, 727, GM 4L60E, 545RFE •  Floor Shift:  Some applications may require the adjustable swivel & the lower rod to be re-positioned to clear the header collector.  See illustration #3703
7.  STANDARD TRANS:	A833 4-SPEED, TKO500* 5-SPEED, TKO600* 6-SPEED, T56 TRANS • Z-bar Clutch Linkage...   67-76 A-body applications must use a hydraulic clutch.  However, DIY Z-bar clearance can be achieved by modifying the mechanical Z-bar clutch linkage.  TTi does not make a clutch linkage to satisfy this situation.   62-74 B-body & 70-74 E-body applications can use a hydraulic or mechanical Mopar clutch linkage system. *Tremec TKO-500/600:  (!) Correct installation of the Tremec Transmissions is imperative.  The output-end of the tail shaft must be in exactly the same position as the stock transmission output shaft for the headers to fit properly.
8.  FLOOR SHIFT:	YES •  Auto Trans:  Some applications may require the adjustable swivel & the lower rod to be re-positioned to clear the header collector.  See illustration #3703
9.  COLUMN SHIFT:	NO •  HOWEVER, column shift clearance can be achieved by modifying your shift linkage.  TTi does not make a linkage to satisfy this situation.

11.  MANUAL STEERING:	Headers clear Manual-Steering & Borgeson P/S units only
12.  POWER-STEERING:	OEM & BORGESON UNIT 67-76 A-body Note:  DIY modification required to the units mounting holes.  The three mounting holes must be elongated to .810" to allow the steering unit to be moved away from the engine for adequate clearance from the header tubes. ◊ Click here to see illustration [7913]

NO – HEADERS WILL NOT CLEAR THE FACTORY LOW-MOUNT A/C COMPRESSOR #4596492AC...  Drivers-side header will not clear in A, B or E-body applications, however, DIY clearance can be achieved in B & E-body applications by making a small indentation in the #1 header tube to clear this factory low-mount compressor.  See illustration sheet #920AC
