yep, i realize this, but i'm already short one piston - likely the one which disintigrated and knocked a chunk out of the bottom of one of the liners, so new pistons, liners and a rebore are all neccesary at this point. luckily the rods appear to be in fine shape....and other than regrinding the big end, the rest looks alright too. so, yeah, total bottom end rebuild, and top end too. ouch!
