Main Cap Bolts

A few days ago, I was preparing to take a 4D56 block to the shop to be rebored. To my horror I discovered that I could NOT locate any main bearing cap bolts. My great fear is that they got tossed (recycled/scrapped) in one of this summer's anti-hoarding jags. No big, I thought, until I started looking around for some to buy: I found a NOS bag of five on eBay for a ghastly price and promptly snapped them up.
Amayama, Partsouq, MegaZip etc. have them for understandable per-unit prices, then shipping, taxes, duties etc. (can we say TARIFFS?) explode that by a factor of 4-5.
Does anyone have any laying around taking up space, or know of a more realistic source of them? I need four of the plain ones (MD020223) and one with the stud for the oil pickup (MD012069).
