To you LNC2-ers who have put the forward facing induction sump on your parallel valve engines, do any of you recall exactly what had to be done to modify the sump, presumably from an IO320B-- , to bring the induction from the rear to the front. Does the casting have a mounting boss on the front? Or did the modification include cutting, welding, etc.? Pictures of the sump, external and internal, would be very informative.
   Incidentally, I understand the IO360-M1A does have a forward facing induction, but it is a fairly recent addition to the family and stray sumps are all but impossible to find.
