It is the same basic strut, but with a metal cap in place of the bellows and an air bladder banded in place. Could use them as-is with a very mild inflation, or take the air bladder and cap off and use the original plastic bellow. If they are new and available, they are worth buying.
Interesting to say the least. No dent for the pinch bolt to have a positive mechanical lock and nearly zero compliance in the upper mount. My former co-worker should have a quote back to me today on the sleeve nut. Someone on a FB Reatta discussion group may donate/sell a bad set of struts to me for starters.
