Okay, I searched high and low for this on multipul forums and web sites. I would like to know if any one has ever resleeved their own block or knows where to find some info on it? I am picking up a B20B block for $30 but it has 2 cracked sleeves. I know I can just get it re-sleeved some ware for about $800, but I would like to try and do it my self and put some 85-86 mm golden eagle sleeves in it. Any info would be much apreciated.
