Nah...I considered it a few weeks ago, but I ordered these parts last Friday and had them 3 day'd to me.  I would've needed to order by Thursday in order to have enough time for full hydro...lol.  I love last minute projects.  I was tired of the stock Toyota pump not having enough balls to work correctly so I bit the bullet and picked up the 1,450psi 4gpm pump, bracket, and 12" heat sink cooler.  I also decided to ditch the V-belt in favor of the 4 rib serpentine to help prevent belt slippage and squealing.  
The heat sink cooler in the pic had a problem though.  One of the brackets was fully welded and the other only had one small tack weld on it.  Being aluminum I couldn't fix it myself so I called up Low Range Off Road and they stuck another one in the mail via overnight UPS so I'll have it today.  If you EVER need anything for a Samurai or Toyota rig you shouldn't hesitate to call (call versus using the site) LRO...they've always taken good care of me!
