Sounds good! The parts are expensive. I ended up buying a complete used Encore Max for about $230 shipped and taking the parts from it. I'm selling the head, box, insert, body and spike to try to make up for some of the costs. One piece of advice when fitting the parts. Make sure to fit everything up before complete assembly. What I mean is take the pins and make sure they fit before attaching them to the shoulder. Don't force anything because the plastic breaks easier than regular plastic. If the pin is too tight, reem it out with a 1/16" drill bit and test it. The pin should move through snuggly to easily. You should not fight it. Also put the tabs of the adapter on a flat surface when you try the pins out. If there isn't a backing the pins could snap. Also if the adapter fits too tightly with the shoulder, shave a little off with an x-acto blade. Again this is so there is no excessive force. Good luck and I'm looking forward to seeing it done.
