I made a complete hydraulic system for my Cobra from off-the-shelf parts from McMaster Carr. If interested, I can send a parts list and photos to your e mail address. Mine is listed above. You will need a drill press and other aluminum metal-working tools (I have a band saw, but a hack saw will do the work too) and some mechanical building experience. If you have those, the total cost will be about $200 and a day's worth of labor. But then you will have a hydraulic jack for your Cobra trailer.

I would very much like to see this parts list. Thanks.

PS - I cannot see your email address "above" in Google Groups version of RAS.
