Yes, I've seen the thread with your pics.
I am very familiar with the process and I've seen that tool [while a mechanic was using it].
The front main seal leak on my car is very very slow; I am sure it will get worse. I prefer to get ahead of impending problems.

Do you have left over sealing compound and the primer? Whatever left over from the job, including the pulley bolts, I will take :-) I guess we just need to negotiate the price.
