E89: Collection of the 7 typical age-related defects in the roof environment

Update 09/2024 Struts / gas springs on the roof as well as on the trunk lid
Roof E89 (BMW 54377212634) Stabilus 0728pb 800Nm (special tool required)
Trunk lid E89 (BMW 51247191255) Stabilus 499514 570Nm
Each pair should be replaced by new ones each decade.
Robbi, These Stabilus struts are reasonable on Amazon -- so it makes sense to replace them while I'm in the mix. What is the special tool required and is it possible to fabricate it?
Edit: I've discovered the tool.. 83302472914 €178.48 at Baum.. -- a bit hefty for a single use tool. From your experience, are there other options to achieve removal and installation without this excess tool cost?
