Buying a National C321 transmission shaft seal for a 1984-1986 Plymouth Conquest can be a viable solution for addressing transmission leaks. Let's examine the potential advantages and disadvantages of this purchase.

1. Cost-effective: Aftermarket seals like the National C321 are generally less expensive than OEM seals. This could save you a significant amount of money, especially if you prefer to perform repairs yourself.

2. Availability: Aftermarket parts are widely available through various retailers, both online and in-store. This makes it easier to find and purchase the seal when needed.

3. Improved Performance: A new transmission shaft seal can help prevent transmission fluid leaks, which can lead to improved performance and longevity of the transmission system.

1. Quality Concerns: Aftermarket parts may not always meet the same quality standards as OEM parts. While some aftermarket manufacturers produce high-quality components, others may not. It's essential to research the brand and read customer reviews before making a purchase.

2. Fitment Issues: There's a chance that the aftermarket seal might not fit perfectly. While most aftermarket parts are designed to be interchangeable with OEM parts, slight variations in dimensions or design could cause issues.

3. Installation Complexity: Transmission shaft seals can be challenging to install, even for experienced DIYers. It may require specialized tools, patience, and a good understanding of the transmission system.

The decision to buy a National C321 transmission shaft seal for a 1984-1986 Plymouth Conquest depends on various factors, including your budget, DIY skills, and the importance of having a high-quality part. While aftermarket seals can save you money and are easily accessible, they may come with some drawbacks, such as potential fitment issues and varying quality levels.

If you're confident in your ability to install the seal correctly and are comfortable with the potential risks, an aftermarket seal could be an excellent choice. However, if you prefer a higher level of quality and want peace of mind, consider investing in an OEM seal from a trusted supplier.

My recommendation would be to research the aftermarket seal manufacturer thoroughly and read customer reviews to ensure the quality and fitment are up to your expectations. Additionally, consider purchasing the seal from a reputable retailer to minimize the risk of receiving a defective or poorly-made part. If your budget allows, I would recommend considering an OEM seal for optimal performance and reliability.
