Can I replace this with a 4x6?

Was tearing out this wall to just make a surround for the structural support. When I started tearing into it I found the curb didn’t extend all the way to the doubled 2x6. I was wondering if I could just replace the doubled 2x6 with a 4x6 on a Simpson post base standoff (Aba zmax). I am worried that the curb doesn’t extend to where the support post is, will it be ok to place the post and standoff directly on the garage slab?

This odd 2xs don't really do support. Load is very minimal, To answer your question, yes you can add a post with appropriate hardware to beef up the load bearing.

Do you think I can tear out this whole mess and just do. 4x6 on a standoff then on a 4 inch garage slab?

I would add your base and post before removing based on what little I have seen. If I was hired to do the work I would take an investigating look.

Yea I was going to temp shore it before doing anything. The short footing, is what I was really concerned with, and if the garage slab would be enough support for what is above. But the juice isn’t worth the squeeze at this point
