Both pieces look to be as good as oem
by Bruce from Plant City, Florida on June 16, 2016
Can't beat the price and service from iboats. Had a delay in the order shipping out on schedule due to availability of one item. Kudos to customer service for resolving with a workaround and getting the parts delivered promptly.
