Passenger side stub shaft seal

[scouty]

New to this page and my first post so sorry if I'm posting in the wrong area.I was changing out my LCA and CV shaft and intermediate/stub shaft today on my 2007 ram 1500. Problem is when I was taking out the 4 bolts that hold the stub shaft seal 3 broke. I was unsuccessful at welding a nut on the broken bolt stub and unsuccessful at using a bolt extractor.
So i replaced the seal and just put the one bolt in. The seal when i pulled it needed to be pryed out. So I'm thinking one bolt would be enough?. What are your thoughts on this?

1 bolt No 2 maybe Lol drill it out be careful re tap it or use a heli coil normally something like that you can get out with a welder but you said you tried.

I seen quite a few YouTube videos where they use 2 bolts. Only I think one video where there were all 4 bolts.
There appeared to be alot of that galvanic seizing.
I'd be 100% ok with 2, I was just questioning 1.
