Simplify Your 1973-1977 A-Body LT Swap with MuscleRods

Achieve seamless integration of the 6.6L L8T motor into your 1973-1977 A-Body chassis through precision engineered mounts and a reinforced crossmember that cut installation time and eliminate alignment guesswork. Made in the USA by MuscleRods, this LT Series AC/Power Steering Bracket kit delivers rock solid support and preserves vintage styling while boosting horsepower, sharpening handling and guaranteeing precise chassis alignment for a truly dependable swap solution.

Complete MuscleRods LT Engine Swap Kit for 1973-1977 A-Body GM Vehicles (Chevelle/Monte Carlo/Laguna/El Camino)

When routing the AC lines and power steering pump on a 6.6L L8T in a 1973 through 1977 A Body chassis, finding a sturdy mounting solution often slows down the project. This AC/Power Steering Bracket is CNC machined from heavy gauge steel to secure both components in alignment with factory holes for the LT series engine swap. By matching original frame rail spacing and engine centerline, installers avoid time consuming adjustments while maintaining correct driveline angles and preserving front suspension geometry. Each bracket ships with hardware and spacers so you can bolt it on and finish the swap without searching for extra parts.

Precision CNC Machining for Exact LT Engine Alignment

The LT Series AC Power Steering Bracket is CNC machined from heavy gauge steel to ensure that each mounting point matches the original frame rail spacing and engine centerline with minute accuracy. This manufacturing approach removes any need for trial fit or fabricating custom shims, allowing installers to drop a modern LT powerplant into a 1973 through 1977 A Body chassis with confidence. Components produced under strict American quality standards hold the engine securely while preserving front suspension geometry. The result is a straight driveline that maintains factory roll center and pinion angle. Installation time shrinks considerably and repeated checks of alignment become unnecessary once the bracket is in place.

Heavy Gauge Steel Structure with Integrated Transmission Support

The conversion kit features a reinforced crossmember and frame brackets formed from heavy gauge steel, engineered to absorb the torque output of Gen V LT engines during hard launches and spirited cornering without flexing the A Body rails. By maintaining consistent load distribution across both sides of the chassis, this setup helps preserve structural integrity over extended use and under track conditions. The built in transmission mount aligns directly with popular GM units such as 4L60E and 4L80E, avoiding major underbody modifications. Each component undergoes domestic fabrication and quality control checks, so installers gain assurance in long term durability. The integrated design also retains the factory bumper mount locations and original rail spacing.

Advanced Polyurethane Mounting for Vibration Isolation

A purpose built polyurethane transmission mount and spacer set reduces drivetrain vibration transfer into the cabin more effectively than conventional rubber isolators, offering a quieter ride and heightened occupant comfort. Polyurethane's resistance to oil and heat ensures steady performance even under continuous load, extending the life of the mounting system. This component aligns precisely with the included hardware pack, streamlining installation without trial and error. It supports a range of LT engine variants such as LT1 LT4 L83 and L86 when combined with the recommended oil pan kit, ensuring hood clearance is maintained. Noise reduction and long term reliability are key outcomes from this design.
