I think I've found a pretty good deal on a complete hydraulic assist setup from WTO. A guy bought it about a year and a half ago, set it on a shelf for a while and then sold his truck. He wants $280 shipped for everything (cylinder, lines, even the ported and rebuilt 2wd box never installed). Since my current 2wd box leaks like hell, I'd like to just bolt up this freshly rebuilt one...plus its already ported. But there's a problem....his box is the older flare style, my truck uses the newer o-ring style. What can I do to adapt over to the old style box as cheaply/easily as possible? Thanks in adavance.
