my first 742 case rebuild, need alittle advice please

Ahhh..this is frustrating well it seems there is three choices here either run the last pattern or buy new gears or try again, I really don't want to discard these gears and honestly they look " as new " I could be wrong but really believe I can get these right or better I know some will dis-agree but my time is free so I'm going to try again with less shim to dry to move the pattern up and I guess if it doesn't work I'll be buying new gears.:BangHead:
