Mike;
FWIW, when I did my own engine I heard about this problem and I, too, have a Melling HV pump so I decided to solve it in advance. I went with 3/16" Chevy pins from MSD (I had to take the distributor out to dinner and get it drunk first!). I punched out the 1/8" pins, set the whole mess up in my drill press, aligned the gear on the shaft until a 1/8" bit slid through easily, ran a 3/16" bit SLOWLY through the gear and shaft to cut the hole bigger, then installed the new pin. Works great.
