End result positive But...
The product had flaws. Two of the lamp seats were misaligned so we needed to carve the key slots so they would accept the sockets and the sockets could lock properly. The screw keepers did not work because there was no thread set. Had to salvage keepers from original part. In the end it worked but the quality was poor. We will see. Price was good but once again, you get what you pay for. These are not manufactured to OEM specifications.
