The Goodmark GMK4141731551A front or center bed floor cross sill is a replacement bed floor cross sill for 1955-1959 Chevrolet and GMC 2nd Series Stepside Trucks. Cross sills run across the underside of the bed and support the floor, so a straight, solid sill is important when the bed floor is replaced.

Goodmark GMK4141731551A Front or Center Bed Floor Cross Sill Features:

• Formed from 14 gauge material and measures 48-3/4 x 2-7/8 x 2-1/4 in.
• Fits the front or center position.

Paint or coat the sill before installation to protect against rust, and test-fit it with the floor before final mounting.

Fits 1955-1959 Chevrolet and GMC 2nd Series Stepside Trucks.
