If you have at least one rear spool, then that's all you need. And, I bought hydraulic lines at TSC for $20 or so... and they have fittings as well there.... I think that $30 total gets fitted hydraulic lines.... I agonized for a long time about using a link with the check valve or not.... since I already had an extra hydraulic cylinder around, I decided to hook it up and see if I had any problems... so far, none... and it's really handy ..... be aware that you wil lneed to select your hydraulic link carefully for length, matching the implements you have... I hooked all mine up with the manual link and adjusted the tilt to max and then min and measured each... and computed what I needed for the length of the connecting attachments to the link I had to make the total the appropriate length. There are several threads on TBN regarding this... suggest you do a search and review if you have not already done so.
