Vehicles with hole ø10.5 mm in rear of tunnel cross piece:

• ‒ → Modify an M10 bolt according to the dimensions given to use as a tool for aligning the exhaust system.
• ‒ Dimension x = 4 mm
• ‒ Dimension y = 25 mm

Vehicles with ø14.5 mm bore in rear of tunnel cross piece:

• ‒ → Modify an M14 bolt according to the dimensions given to use as a tool for aligning the exhaust system.

• ‒ → The attachment bolt on exhaust pipe must be parallel to tunnel cross piece
• ‒ Dimension x = Dimension x
