12.  STEERING:

YES, POWER-STEERING or MANUAL STEERING

• Borgeson Power-Steering Unit:  Mounting holes may require elongating to allow the steering unit to be moved away from the engine for adequate clearance from the header tubes.  (See illustration sheet #7913)

• 67-76 A-bodies Only / Steering:  This header will not clear a Quick/Fast Ratio Pitman & Idler arm that is longer than the OEM arms.  Example; The Fast Ratio Pitman & Idler arms by Firm Feel, Inc. are 3/4" longer then stock.  DIY clearance can be achieved by dimpling the header tube(s), however, doing this modification will void your header and coating warranty.  (This note pertains to 67-76 A-bodies only.  Headers will fit B & E body applications with Quick/Fast Ratio arms)

INSTALLATION INSTRUCTIONS

A-BODY / STANDARD TRANS APPLICATIONS:  MODIFIED DESIGN Z-BAR

• A modified design Z-bar for 67-76 A-body applications having header clearance issues using the OEM/Stock Z-bar.  (See illustration sheet #340ZB)

• Z-bar available for use with TTi header no: 340A

(!) Not available for all header/vehicle combinations

# ZB340

$ 133.50 each

COLUMN SHIFT APPLICATIONS:  B & E-BODY TORQUE SHAFT ASSEMBLY

Due to various manufacturing designs of the column shift linkage in some 71-74 B-body and 70-74 E-body vehicles, a modified design Torque Shaft Assembly may be required.

A Torque Shaft Assembly is required if the drivers-side stock straight torque shaft rod is mounted below the torsion bar.  The stock straight torque shaft rod passes directly through the space where the header tubes or exhaust pipe to manifolds, must go.

This precision bent assembly with laser-cut ends allows you to maintain your column shift linkage, and is a direct bolt-on replacement of your stock torque shaft rod.  [Illustration sheet B7174TSA .pdf]

HEADER GASKETS

HTX-900 gasket material:  A high density non-asbestos fiber metal core composite consisting of graphite coated, hi-temperature facing material chemically and mechanically fused to an expanded steel core.

A proven hi-performance exhaust gasket composite used extensively within the automotive racing industry, where characteristics such as structural strength and hi-temp load retention are required to withstand severe under-the-hood operating environments.

Recommendation:  Permatex 81160 gasket silicone sealant.  Use a very thin layer of Hi-temp silicone sealer on each side of gasket.

Note:  (2) Supplied with header purchase.
