Garrett 028145702: Which one fits?

As a newcomer to this forum, I would first like to thank you for the high quality of information provided.
We would like to thank the person who reported this issue. A loose crankshaft gear could be identified and more serious damage prevented.



After 180,000 kilometers (approximately 112,000 miles), of which 105,000 kilometers (approximately 65,000 miles) were with an aftermarket tuning module installed, the VTG (Variable Turbine Geometry) mechanism is no longer functioning properly. If the methods described here do not provide a permanent solution...
To improve the situation, a replacement is probably necessary.
Money naturally plays a role . The Garrett VNT 15 028145702 installed in my vehicle.
It should cost €795 including the mounting kit (for an exchange).
I have this type of loader available, but with the following suffixes: R, H, C, and G. I can offer it for exchange starting at €300.
seen?!
Which of these types is compatible with my vehicle, or which one requires the fewest modifications? (Or where can I find the original part at the lowest price?)

Vehicle data: 1HXO, Key slot 2: 0600, Key slot 3: 27900E6.

Thank you in advance for any tips and suggestions!
