|Do I need to replace my automatic pedal hanger (bracket) with a manual hanger?
In most cases, the answer is NO (excluding 73-87 Trucks). Some models used two part numbers, with one for power brakes (power booster) and one for manual (no power booster).
Should my car have a brake pedal return spring?
If you have power brakes (power booster) NO, if you have manual brakes (no power booster) YES.
Should my car/truck have two return springs?
If your model has the clutch pedal return spring from your fork to your frame the answer is NO, if the return spring is attached to the upper zbar lever YES.
