These bolts can be expensive. I've priced them with just a few vendors that were willing to even talk to me about such a task of machining them. Trick Titanium was one of them and it was expensive per bolt. They are not regular store grade bolts in size, shank shape, strength etc.
I think they were to be $25.00 per bolt or some thing like that.

I believe my four only cut off 1/2 a pound or so, but my madness was full blown as Hemi-itis says.
These bolts are special and if you are going to have them on your most important frontend segment, The K, then they should be made the right way like to ones from prochargedhemi here. After all, they do hold up the K member itself to the front longitude frame.
Be crazy out there, but be realistic and practical to a certain extent.
Note the aluminum crush cone washers on the strut rods.
