Based on the information provided, here are some suggestions:
Clutch Resurfacing: If your clutch is not slipping and the only issue is the leaking slave cylinder, you may not need to replace the entire clutch assembly. Cleaning or resurfacing the clutch may be sufficient. However, it's essential to assess the condition of the clutch components and consult with a professional mechanic for an accurate evaluation.
Ordering Parts: If you have already ordered a clutch kit, friction disk, pressure plate, slave cylinder, and rear main seal, it is possible to stop the shipping of the flywheel if you don't need it. Contact the supplier or retailer as soon as possible to request the change.
CV Seals and Axle Nuts: If the CV seals are not leaking, it may not be necessary to replace them. However, if they are worn or showing signs of leakage, it's a good idea to replace them to prevent future issues. As for the axle nuts, if they are worn or damaged, it is recommended to replace them for proper axle retention and safety.
Flywheel Bolts: Reusing flywheel bolts can be done if they are in good condition and meet the manufacturer's specifications. However, it's important to ensure proper torque specifications and consider the overall condition of the bolts. ARP 6-bolt kits are aftermarket options that can provide enhanced strength and reliability if desired.
MTX-75 Transmission: The MTX-75 transmission is commonly used in various Ford vehicles. While specific experiences may vary, it's a well-documented transmission, and many professionals have worked on it. Consulting a reliable automotive technician or referring to reputable resources can provide guidance during the repair or replacement process.
