Can anyone give the specific size variations of the bearing shells for both mains and conrod please? Standard sizing with all possible colours?

big ends have only one size, per size where as mains have 3 different colour classification per size of shell

So bigs come in stock 45mm size red and blues (red fits in the cap, blues in the rods) then you have +0.25mm reds and blues then 0.5mm reds and blues.

mains are stock 65mm iirc so white, green and yellow. They're for a stock size main end but they are in fact all slightly different sizes.

Then the same for +0.25mm come in white,green and yellow. Then same again for +0.5mm shells
