This kit was specifically designed to fit Chevy A-Body cars. This is a front steer center take off style rack & pinion mounted on a one piece bracket that bolts in the same mounting holes used for the factory steering box and idler arm. The rack matches the stock suspension on these cars replicating the original center link.
The kit clears the Z-Bar and 4 Speed Linkage. The kit has been used on both Small Block and Big Block motor cars. Stock Manifolds work with both motors and on Big Blocks, we have used Super Comp Headers while on Small Block Motors, Hooker Competition Headers have been used. Other headers may work, but may need modification.
Shaft kits are included in both small block and big block kits, and require using 3 u-joints and support bearing. Pump kits are also included; the big block motor pump kit uses a matched pump, single V-groove pulley, bracket, and remote reservoir. The small block , motor pump kit includes a matched pump, single V-groove pulley, bracket, and clip-on reservoir.
Note: Most Aftermarket Heads have raised exhaust floors by 1/4" to 1/2" which does not make clearance any easier.
Note: This kit will also bolt into a 1964-67 big block El Camino.
A special note on big block motor cars: There are several different designs, Mark IV, Mark V, and Mark VI. The original Mark IV design has a deck height of 9.8", the Mark V and Mark VI designs have a deck height of 10.2". The 0.4" difference affects clearance on these big block cars. Mark V and Mark VI designed cars will probably need header modification.
