Hello all.

Well, I'm to the point of reassembling my B20B/E for my 122s and lo, the rods are not the same! Three have only a "630" or "610" cast on them and the other has a long string of numbers and letters. When I weigh the units I find that the odd one out weighs some 30 grams less than the others. I trip out to the junk pile and strip the old B18 and find rods (matched set but #4 horribly burnt from a spun bearing) with "123" cast into them and the sharper shoulder at the bolt head (also they weigh yet another 100 grams less than the others!).
Grrrrr. Does anyone have a spare rod in decent condition they can sell to me or trade for this "light" one? Or maybe a matched set of pre 1974 B20 rods (22mm wrist pin)???
The weights of the B20 rods are; heavy, 734g +/- each; light 703g +/- with bolts and nuts.

If you are willing to lend a hand give me a hello at mjamgb@sbcglobal.net

Thanks all,

Mike!
