Posi-Lok 4X4 Front Differential Device

[MRogers]

I'm sure many of you have heard of this product before. It basically replaces the factory vacuum device that connects the passenger axle to the front differential with a manual pull handle that mounts under the dash.

I was wondering if anyone here had one, and if so, if you liked it and how well it works. I was also wondering since the vacuum system isn't used, if it was posible to completely remove all of the vacuum (not vent) lines from the t-case. I just like to get rid of things that aren't necessary.
