ok, i just did the lightened pull and the backslack mods on my Rodeo and they work great.
I need to add though, that anyone doing a mod that requires knocking out the trigger and sear pins, find a way to block the saftey on both sides. At somepoint in my work, i felt the slide for the safety slip past my finger and heard something hit the wall behind my tool box. All i can figure is that the jolts going through the trigger frame were enough to somehow push the detent ball and sping down enough to let the slide past and therefore released the tension on the spring which shot both the ball and pring out of my gun.
Luckily after some careful searching i found the ball on the ground under the table next to me. to give you an idea as to how small this ball is, the hole that these pieces fit into are just big enough to allow a 3/32in punch through to push the ball down enough to slip a flatblade screwdriver in to keep it down enough to slip the safety pin back in.

IF YOU LOSE THIS BALL OR SPRING YOU ARE ****ED! THESE PARTS ARE NOT LISTED IN THE DIAGRAM SO YOU WILL HAVE TO GET A NEW TRIGGER FRAME!
