Thank you for taking the time to share your feedback. We are sorry to learn you have experienced an issue with your seat. We take a pride in manufacturing quality products, so it is unfortunate when the seat does not meet the consumer's expectations. The white bushing will only fit into the mounting holes once installation is complete. The StaTite fastening nut will essentially pull it into place once the nut has been fully tightened, ensuring the bushing is snug in the mounting holes to prevent the seat from wiggling around. Please contact our customer service at 1-888-722-6488 and reference CASE# 277460 if you would like to discuss your concerns. We look forward to hearing from you.
