Dan: I think the safety assembly is the same as shown here:https://www.gunpartscorp.com/gun-manufacturer/lc-smith/old-mdl-hmrls-lcs, specifically parts 11, 12, 40, and 41.

Can this be done without disassembling the entire gun? Can I get at this from above without removing the trigger assembly? If I need to remove the trigger assembly, this means I need to deal with the lever mainspring again when I put everything back together again. I'm trying to avoid that.

I think I see how it goes together, but I think I trip the safety link (part 40 in the diagram).
