While I could have kept the screws, one of the heads were pretty messed up from being removed with a smaller screwdriver in the past. So I ordered new ones.
Here's the spec if anyone needs it. I just purchased the fastener from a supply house, but you could get it from the dealer.
M6 x 1 mm Thread, 10 mm Long, Brass.
MB part number N 000 000 000 117 ($2.60)
Then I pulled the junction block, scrubbed it, and cleaned the contacts. The area underneath and around the junction block had some surface rust, so I wire wheeled the area and painted it with Rust Encapsulator. I might paint it later if I ever get around to making the engine bay prettier.
I won't lie, having new heat shrink, a new ring connector, a painted surface and new brass hardware made me feel all warm and fuzzy inside when it was all put back together.
