2011 386 broken steer shock stud help!!

I was replacing the steer shocks on my 2011 386 and sheered off all studs but one upper. The lower mounts don't appear to come out easily which are part of the spring saddle and look pressed in with no bolt hole on back side. I was considering replacing the studs but am cautious as most bolts I put a wrench sheer off due to rust. I'm working on tapping them to just put a regular grade 8 bolt in the stud end which is a pain in the arse since the metal is so hard. I'd love any suggestions as it's getting frustration. If there's any way to relocate them I'd be interested in that as well.
Thank you in advance for any help and suggestions.

 

Awesome, thank you!!

 

Looks like I can't PM him as I'm new and TR requires 7 posts before I can make a visitor msg.

 

Cool, many thanks.

 

Ya, I bought grade 8. Not from Cat as they're far away so Ace Hardware had to work.
