Outside Door Handle Kit Smooth - Front Driver Side (LH) - Fits BMW 99-03 X5 E53 | eBay

This is for a handle for 11.00 or so shipped. It came with the two part handle, two gaskets, and the two parts you are looking for, 19 and 20. Maybe it was a fluke that it came with the bolts, but you can ask the seller if that is normal.
