What a bummer! Yeah I recently tried to just get new magnum main bolts and those are out of production as well. I will definitely be hanging onto that main bolt in light of your post.
I found it weird that kevko doesn’t direct you that you need one in the oil pan information page. I would have just done a line hone with main studs from the get go had I known. I was already way past machine work stage when I went to install the pan.
I wonder if you could just run that arp and torque using oil and treat it as if it were a regular main bolt?
