Sizing a floor plug
A floor pan plug closes an opening in the floor, usually a hole left after a seat, pedal, or accessory was removed. Measure the opening before buying so the plug seats flush without forcing it. Clean the edges of rust and debris first, because a plug fitted over corrosion can trap moisture underneath.
Choose between drive-in and press-in styles based on how the opening is shaped. A plug that sits flush keeps water and road spray from collecting around the edge, and sealant around the rim can improve the seal. Check the plug after the first few drives, and reseal if the edge has lifted.
