I had a whole reply typed up but somehow I must have hit the wrong button and it got lost. Here goes again...
The whole quadrant thing is pretty easy to install. The only caution I'd make sure you understand is that my prop governor cable isn't routed per plans. So don't copy my cable lengths unless you are going to drill the same hole and use an eyeball in the firewall in the same spot as I did. If I were doing it again I'd move it up 1/2", but that would mean a longer cable. If you have an extra inch of cable, that's a LOT...these things are very stiff. So you want to get the measurement pretty darn close. I think before I offered to send one of my cables to you if you want to use it to measure for your own cable lengths. Just send it back or to the next guy who needs it when you're done. Once a couple other people install it, I'll feel more comfortable that it'll all work well for you. If someone routes the Prop cable per-plans with a quadrant, post what cable length you used so that others can know that too.
Also, if you plan to go with a quadrant, there's really no need to get it before your FWF kit. I would order it when you order FWF components. Install it before you put the upper forward skin on. The only other thing that could get you stuck is that center pedestal to the subpanel. Check out this photo:
You'll notice that the center of that pedestal is all cut away. That's to give clearance for the quadrant and cables to route out. If you KNOW you'll do a quadrant you can cut that ahead of time. Otherwise, maybe just don't rivet it in until you fit the quadrant. There's no reason you can't rivet it in later...especially if you use pop rivets or screws. That way you can sort of do this whole install at once.
With the FWF kit, you should get most or all of the rod ends you need, so you just need to exclude the push-pull cables, buy those yourself, and get a quadrant and clevis' and clevis pins. Buy yourself 100 quantity of cotter pins and light washers in all sizes from spruce because you can always use more cotter pins and washers. Then you'll have everything you need to do the install (other than the eyeball passthrough if you do that too). I really like how the eyeball passes through the cable.
So good luck, and if someone else does install one, post back how it goes. When you're all done I'm betting you love it.
One other small tip:
When you buy the quadrant, it tends to make an aluminum sliding noise when you move the levers. On both planes, I cut small pieces of UHMW tape and stuck them to the levers, right where it rubs the slot. This cuts out any scraping noise. It's a real smooth quadrant.
