Another lets play "ID these parts"

There are a few aftermarket examples of longer, fast ratio pitman and idler arms. Firm Feel and Hotchkiss sell them. I believe PST did also, but I don't see a listing currently. Proforged makes them, and they've been on Rock Auto recently, but they're not listed now. Covid shortage? Proforged is on Amazon, but I don't trust their application guide.
Matt Ross at Firm Feel told me their arms are 1.5" longer, which would have hit my stock 340 exhaust. Maybe this will help.
