318 tear down... it’s about time.

And yes the 496 rods are quite a bit beefier than the 699s; I think the weight difference in them might be up to 100grams.
758 grams versus 726 grams. Weight is mostly in the beams, from what I recall (I have compared sets of both). The bushed 273/318 rods also were under a 2406782 PN.
