Need help with fittings please.

[crusher]

I am building a 4 valve block for my excavator, it is almost the same one shown on this site earlier, my problem is the ports to go to the cyls are only about 3/8" apart center to center. I have spent hours on the net trying to come up with push lock fittings ( 1/8 tube into 10/32 thread ) I have purchased two sets of fittings however neither will mount side by side in the manifold. I see parts made by others showing fittings with a knurled pattern on the outside, cannot find them.
Any help would be much appreciated.
Thanks
Terry
