I think that the 5.7 probably works slightly diffrent than the 5.2.
Is there anyone out there with a 5.7?
Murrays sells a conector kit for the H-20 that I adapted to work on my solcat 18 with considerable effort. Its the only thing that I have seen that looks like it would work. However, I dont know if the tube dimentions are the same on the H-20 as the N-5.7.Does anyone out there have an ansewer for that one?
