Floor Jack Transmission Adaptors

I have to remove a 4R70W from a 1995 Crown Vic. I have found four
different adaptors to fit floor Jacks and was wondering about
recommendations, are these adaptors generally safe?:

There is also a really cheap transmission jack:

Thanks so much for the information. I am going to rent a transmission
jack twice.

Look into buying one from Harbor Freight. While they do sell cheap
tools, the occasional use is just fine. I have a tranny jack from
them and have used it several times in my vette.
