T-Bolt for Side Trim Moulding
Sold each

The OE Match Side Trim Moulding T-Bolt is a replacement fastening component designed to secure the exterior side trim mouldings on applicable Porsche 356 models.

Fits:

  • Porsche 356B 1959-63
  • Porsche 356C 1963-65

Diagram ref no 9

Its T-shaped head fits within the trim moulding channel, providing a concealed fixing that helps maintain secure attachment and correct positioning of the decorative body trim.

What Does It Do?

The T-bolt secures the exterior side trim moulding to the vehicle body.

Its concealed mounting design allows the trim to remain firmly positioned without visible external screw heads.

Why Does It Fail?

Common causes include:

  • Corrosion and rust
  • Damaged or stripped threads
  • Wear from vibration
  • Overtightening during installation
  • Damage during trim removal

When Should It Be Replaced?

Replace if the T-bolt is corroded, bent, loose or has damaged threads.

Replacement is recommended when removing or restoring side trim mouldings, particularly if the original fasteners cannot be reused securely.

Checks & Installation

Inspect the moulding channel, mounting holes and associated fixing hardware before installation.

Ensure the T-bolt slides correctly into the trim channel and is positioned accurately before tightening. Avoid overtightening, which may damage or distort the moulding.

Key Features

  • OE Match replacement side trim T-bolt
  • Concealed fastening for exterior side mouldings
  • Suitable for applicable Porsche 356 models
  • Fits Speedster, Convertible D and Roadster applications
  • Also suitable for optional Coupé and Cabriolet side trim
  • Included in the side trim hardware set
