Notes

Spindles

  1. The Mustang II spindle has been used in street rod applications for years. As such, many brake kits have been developed for them. One can get kits with rotors of 9-1/2", 10", 10-1/2" or 11".
  2. Caliper choices are full size GM, orginal Ford, GM Metric or Wilwood. Bolt patterns are available in 5 x 4-1/2", 5 x 4-3/4", and 5 x 5".
  3. The biggest brake kit we offer for this spindle is #91031943, with 1969-1972 Chevelle 11" rotors, full size calipers and standard Chevy 5 x 4-3/4" bolt pattern.

 

Control Arms

Why go with tubular control arms? The most obvious reason is the looks. Tubular control arms and strut rods give your hot rod a much cleaner and hi-tech appearance than the stock type do. Another bonus is that the tubular control arms are available in 5/8" narrower than stock, which helps tuck the wheels up under the fenders without having to buy expensive special offset wheel. When using 5/8" narrower control arms, 1" must be removed from each inner tie rod end.

 

Crossmember

This bolt in unit is ONLY made to fit a 47-54 Chevy 1/2 ton and 3/4 Pickup chassis. Inside dimension at axle centerline is 23-1/2", outside is 28". This frame is slightly tapered to the front. Standard MII spindles will set pin at 1/2" below frame rail and 2" drop will set it at 1-1/2" above. Track width is standard 56-1/2" depending on which brake kit is used.

 

Steering Rack

  1. The Power Steering unit has 5/8" and 9/16" O-ring style ports. If you have an inverted flare fitting on your existing lines, that will not work.
  2. The Power Steering unit can be used with our standard GM pumps 91032922-GM, 91032908-BLK & -CHR, and with hose kits 910-32535 and 617-4835.
  3.  Applicable Bump Steer Kit # 721-BAX102 now available when application may require.

 

Proper Break-In Procedure for Steel or Cast Iron Rotors

New steel/iron rotors should be bedded in before being used in racing conditions. Proper bedding will prepare the rotor surface, prolong the rotor's life, and make it more resistant to thermal checking or cracking under severe braking conditions. The following procedures should be performed when bedding in both steel and cast iron rotors. It is best to bed in a new rotor using a used set of pads, preferably ones which will not create heat rapidly. Generating heat too rapidly will thermal shock the rotors. Likewise, when bedding in a new set of brake pads it is best to perform the process on a used rotor. This new/used bedding process permits controlled bedding of each individual component.

Make sure rotor surfaces are free from oils, grease, and brake fluid. Run vehicle up to a moderate speed and make several medium deceleration stops to heat up the rotor slowly. This will help reduce the chance of thermal shock caused by uneven heating of the rotor. Pull into the pits and allow the rotor to cool to ambient air temperature. Care should be taken not to ride the brakes into the pits as this may hot spot the rotor causing premature wear to the surface or structural damage.
