My sack of lemons....
Got the oil jets modified to fit with the 4.05" stroke. What a PITA but once I got past the first one they all went OK. I MIG welded them after shortening them and drilling out the bodies with a 5/32 bit. Then re-bent them to my eye ball. Here is a pic with a new 6.4 squirter sitting on top of one of my modded 6.1 squirters. Still gonna need a baby notch in the piston skirts.
