WTR Rear Diff Input Shaft Seal Tools

[Albino09]

My M3 has developed an input shaft seal leak on the rear differential. After researching the repair, it seems there are 3 special tools that BMW/FCP Euro sells.

1. BMW Pinon Flange Counter Hold Tool
2. BMW Pinon Seal Driver Tool
3. BMW Differential Pinon Flange Adapter
4. BMW Pinion Flange Installation Tool

Does anyone have any of these tools already purchased that they'd be willing to rent to me? I'd rather not spend $400 in tools to replace a $15 seal if I could help it.

Also interested in these kinds of tools -- I have to do a diff output seal and would love to have the right tools to pull the old seal out and install the fresh one. It was a royal pain in the ass last time iirc.
