Yeah, well, so much for Rock Auto. For the 2005 Crossfire they have 2 struts listed under Body…Lift Support.

One is a Monroe 900118 Max-Lift. The listing says it's for "Coupe; Hatch".

The other is an AMS Automotive 6189. It says it's for "Trunk".

The convertibles have trunks & the coupes have hatches, right? So I ordered the AMS. It arrived today. Wrong part. It's obviously for the coupe hatch also. It's going back as a return.

My conclusion? If you need convertible trunk struts, go to Advance & pick one of the Strong Arm struts. Maybe by trial & error somebody will eventually discover the best amount of force.
