Or what should I Use? second question The impeller housing appears to have been cleaned and modified to accept three new mounting bolts one is 1/4-20. when I bolt the housing down it appears to squeeze the impeller in the vertical demension. any thoughts on repair or remedy. The wear plate is new and was modified to accept the new mounting bolts. I finished the new bronze wrist pin bushings last night and with your HELPPPP!!! I am looking forward to showing all of you some pictures of a smoking new baby.
