Buying a GM 1973621 nos vacuum distributor for your vehicle can have several pros and cons that you may want to consider before making a purchase.

1. OEM Part: This distributor is a new old stock (NOS) original equipment manufacturer (OEM) part, which means it is an exact replacement for the original component that came with your vehicle when it was manufactured.

2. Reliability: Since it is a new part and not rebuilt or refurbished, it may offer better reliability and longevity compared to used or reconditioned parts.

3. Performance: A new distributor can improve the performance of your vehicle by ensuring that the right amount of fuel is being delivered to the correct cylinder at the right time.

1. Cost: New OEM parts can be more expensive than rebuilt or used parts, so the cost of this distributor may be a consideration.

2. Availability: Since it is a NOS part, availability may be limited, and it may take some time to find one and have it shipped to you.

3. Installation: Installing a distributor can be a complex process, and it may require specialized tools and knowledge. If you are not comfortable doing the installation yourself, you may need to pay for professional installation, which can add to the cost.

The decision to buy a GM 1973621 nos vacuum distributor depends on your specific needs and circumstances. If you value the reliability and performance of an OEM part and are willing to pay the price, then this may be the best option for you. However, if cost is a concern or you are comfortable with a used or rebuilt part, then you may want to consider other options. Ultimately, it is important to weigh the pros and cons carefully and make an informed decision based on your budget, vehicle needs, and personal preferences.

If you decide to purchase a GM 1973621 nos vacuum distributor, be sure to buy it from a reputable dealer or supplier to ensure that you are getting an authentic OEM part.
