Hello I am in need of a set of BBBB Pistons, I have a set of AAAA pistons which I could swap if anyone wants to. My block is BBBB so I bought the wrong ones

Dont think I have a spare set

absolutely no idea whether they are A or B sorry, the top marking on the piston on all x4 have completely rubbed off

i guess the only other way of telling is by measuring it?

I think the A's have no marks, but the B's are stamped.

FWIW I measured AAAA pistons at 86.1mm
