So the Sss doesn’t just use the factory screws to mount it. You have to make extra holes. Right?
It uses all if the factory holes and then 12 additional holes you have to make. You can either use self tappers or drill/tap for bolts. 8 of the holes are in the round lower side rails and 4 are into the inner frame rails.
From having just done it, I can tell you there isn't a ton of material to run a tap through, however, I just came back from PTO and not a single one came loose much to my surprise. At every stop I was checking the thing because I was certain one was going to pull loose.
The SSS A-arm skids leave something to be desired though.
