It's actually very easy. I changed mine on my '93 Dynasty from the top. There's a 15 mm nut on the mounting plate behind the tensioner's pivot bolt. The problem is you can't turn the nut far enough to grab it again with the same wrench. Use two box wrenches from different manufacturers so the points are in different positions, first one wrench, then the other one until the nut is turned about one turn, then it will spin off with your fingers.
Normally this is done from underneath behind the cross member, but there's room from on top on Dynastys.
