Hey there! Great mod! Thank you for your great work! I recently (finally!) got a tropo and tried to upgrade it's saddle. It will not allow upgrade to tropo saddle. Also I was wondering is it possible to also upgrade scuba gear? Actually wait I just realized I'm using lethals re-useable scuba so perhaps that might be the issue? I will check ... ALTHOUGH ... I'm pretty sure I was able to upgrade Lethals reusable hazard suit tho ... just asking. Thanks again!
