Default Converting GM part to Inverted flare fitting size?

I searched this site for a conversion but can't find any info on the inverted flare fitting that fits in the 4L60E tranny for the cooler lines. The GM Part # is: 8637742. Anyone know the equivalent part/size at Summit or Jegs?

Should be 5/16 inverted flare for the fitting thats on the hard line, 1/4 npt for the fitting that threads into the case.

If you try to screw 1/4" NPT in you may crack the case. It is not supposed pipe thread.

This should be what you're after. http://www.summitracing.com/parts/ATI-925137


I realize this is not exactly what you're after, but it's what I've used in the past.
