my first 742 case rebuild, need alittle advice please

Thanks for all the thoughts funny for some reason I was thinking of calling gm to I will do that tomorrow but as far as the pattern goes I guess it's not clear enough for any thoughts? I am going to try again I am at 66 thou now and too high on the drive side so I will add a couple and see getting good at takin it apart lol but getting a little boring now
