My new to me MS6 was missing a few things when it arrived. It's missing both tow hook covers and both of the exhaust rings that fit into the rear bumper. Before I order them, am I correct that what I need are parts #24 and #27 (two of each) in this diagram? Honestly I'll probably look for a wreck MS6 for the exhaust rings because $272 is a bit steep for two tiny parts.
