Help Needed – 1971 Challenger R/T

Hello all. I am new to the group and in need of a little advice/direction. I am a girl who has just bought her first muscle car and all the men (mechanics) I meet give me contradicting advice on how to fix my car. If anyone could tell me their experiences on the below issues and provide advice for the best products to use for the E-Body - I would really appreciate it.

1. Ignition systems: Accel, MSD, or Mallory? I currently have Accel but when people look under the hood they all shake their heads. One guy says that Mallory is best as long as you have more than one ground.

2. Converting manual front drum brakes to Power Disk with a booster - Which kit to buy? Don't want parts from China (which is a risk if you order from Summit) One mechanic says to piece it together...One mechanic advises a $1,300 kit from PST and then wants to charge me $1,000 to install. Ceramic or semi-metallic pads? One guy recommends "Brembo" with a minimum of slotted braked.

3. Is it ok to replace one window? Someone must have done some interior work to the car and there is a sandblast/pitted residue that won't come off the passenger side window. Windows are $200 a piece - even the back triangles. But it is only the passenger window that is bad.

4. Carburetors - A tricked out Holly 750 HP-S (no vacuum) or 770 Avenger Series (w/vacuum).

5. Headers - TTI Ceramic coated or normal Hooker Headers?

6. Spark plugs - Is it true that you cannot use Platinum plugs in these cars?

7. Oil - One mechanic convinced me to switch out to Royal Purple Synthetic Blend, but other guys are telling me Mobile One is the way to go.

I know that everyone has their own way of doing things and that opinions are very subjective - I am hoping that the members of this website have gone through similar problems and that I can benefit from their experiences. Money is not the issue - I just want it done right - the first time - so that I can enjoy the car now instead of spending all my weekends at a mechanics shop funding their retirement! Being a girl has it's disadvantages.

Thanks in advance.
