One of the trim cylinders on my 1997 DP-S drive is leaking from the seal on the piston rod. This model has the older style trim cylinders (with the plastic cover on top and non-chromed ends). There is a "kit", P/N VOL3885196, which I believe has the newer style trim cylinders with new lines. Does anyone know what all is included in this "kit"? If the trim manifold has to be replaced this may be a bit more work than I am willing to accept. Thanks!
