LA top end rebuild question

Question was anyone set one up and how did it go and was it a worthwhile upgrade? Ill say yes to both. It takes a motor on a stand to install correctly as you have to mock it up and then mark the bolt you have to drill and tap. You also have to get the backlash correct (iirc 6-8 thou) and its no fun in the car. To set backlash they use a piece of newspaper between the gears and then you press the gears together and then tighten top bolts, then you drill and tap the new bottom hole. Bottom hole is more for saving your lash and very small adjustments. using a mic afterwords to make sure your between 6 and 8 thou. CAT used to make a decent one but its long out of production. IIRC Milodon is the only game in town for the LA Mopar.
