Sold each.
Fits:
Porsche 993 C2 1994-98 MANUAL (Gearbox type G50.20 / G51.21)
Porsche 993 Carrera RS 1995 MANUAL (Gearbox type G50.31 / G50.32 / G50.33)

Diagram Ref No 15.
Bolts used in drivetrain and gearbox assemblies are exposed to continuous vibration, torque stress, and environmental factors such as heat and corrosion. Over time, these conditions can weaken or stretch the bolt, reducing its ability to maintain proper clamping force. Using a degraded or mismatched bolt can cause mounting misalignment, vibration, or even component failure under load.
When to replace:
• During gearbox or silencer block removal, when original bolts show corrosion, wear, or damaged threads.
• As part of drivetrain servicing or restoration, ensuring all fasteners meet factory torque and material specifications.
• Whenever hardware is reused or mismatched, to maintain the correct preload and structural integrity of the assembly.
Replacing this hexagon-head bolt guarantees the proper tensile strength, precise thread pitch, and corrosion resistance — restoring safe, vibration-free mounting performance in your Porsche 993 Carrera 2 or related 911 model.

Information
Transmission case rubber mount
The transmission mount helps hold the manual gearbox in place, ensuring it stays securely positioned under side load and torque. It also absorbs engine and drivetrain vibration, preventing it from transmitting into the cabin or other chassis components. By maintaining proper transmission alignment, it supports smooth gear shifting and reduces stress on linkage and drivetrain parts.
Fits:
Porsche 356 1.1-2.0L 08/1950 - 04/1965
Diagram ref no 49
Installed between the transmission housing and the vehicle’s chassis or subframe, this mount:
• Secures the manual transmission in its correct position
• Dampens vibration and noise from the drivetrain
• Helps maintain accurate drivetrain alignment
• Reduces wear on surrounding mounts, brackets, and hardware
