The Goodmark GMK4144731732A front or rear bed floor cross sill is a replacement bed floor cross sill for 1973-1987 Chevrolet and GMC C/K Fleetside 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 GMK4144731732A Front or Rear Bed Floor Cross Sill Features:

• Formed from 14 gauge steel and measures 72 x 4 x 3 in.
• Fits the front or rear position on Fleetside models only.

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

Fits 1973-1987 Chevrolet and GMC C/K Fleetside Trucks.
