Thanks Bob-

  I wanted to make some accurate measurements before I responded. To do that 
I made a gauge from some 3/16" stock drilled size "D" so a screw shank was 
held firmly. I inserted the screw into the flange holes on the gear box 
along the bottom and checked to see if the gauge lay flat on the flange. On 
the rear strip 5 of six holes were crooked, one noticeably worse than the 
others. On the front flange, most holes I could reach were fine. I did find 
one that was way off. I still have some screws installed so I haven't 
checked them all.

 I agree that the gear box assembly seems to be well made- I think the 
quality of the parts Lancair supplies is outstanding. The trouble is in how 
the box was attached to the fuselage. It may be a problem with my kit alone 
but I thought it was worth mentioning. -Bill Wade
