"Thanks Bob, next question would be the upper over fill screw on the lower unit seems to have lost its threads. I was replacing the lower unit oil yesterday, got to the top hole. Went to put the screw back in and there is nothing. I am not sure what to do at this point, do I need to drop the whole lower unit? And what do I do about threads now? Wehn I get home today I will post some pics."
 
"Are there good threads deeper

"Are there good threads deeper in? I recently replaced a stripped plug on my stringer drive upper housing with a stainless steel header bolt from a performance car place (for a 350 chevy). Same 3/8 coarse thread and about a full inch long, so lots of bite and nice flat surface for the seal washer.

I just made sure I had enough depth for the bolt without hitting a gear or anything - I was fine for clearance"
