Here's some pics to see.
1. Front view spindle with bearing adapter installed
2. Side view spindle w/bearing adapter (Note: redrilled zerk & setscrew)
3. Front View w/Caliper bracket installed
4. Side view w/Caliper bracket installed. Note I also turned around the spindle locking bolt for more clearance.
I've got the bearings, seals and rotors in the shop ready to install, but the calipers won't be in until tomorrow.

installed a kit from mid-fifty,I think it was a CPP kit,struggled with the bearing adaptors like everyone else. used alot of emery paper and heat.My kingpins were good so I had to relocate the grease fittings with the spindles assembled.drilling the spindles was difficult,the spindles are soft,but the bit buttoms out on the kingpin which is harder than hell.need a lot of patience,drill bits,a bench grinder,had to make bottom taps and drills.I have a 54 f250 spindles are same as f100

I didn't have to drill and tap mine for zerks. It's been a couple of years but I think all I did was install a zerk with a 90 degree angle. My kit came from ECI but it sure looks the same.

Bobby on one side straight or 90 degree fittings will work but the other side has to be moved. I have heard of people notching the caliper brackets but I did not feel comfortable going that route.if you have a choice,drill the spindle without the kingpin installed,for a good clean hole,good grease flow,I really struggled with the last couple thousands of a inch of metal to get a good clean hole.

I think CPP's directions could be a lot better in some respects. Some more pictures would help out a lot.

I'll take a closer look at it the next chance I get

Well, we got a little bit of progress today, but I'm waiting on 2 spindle washers to arrive via carrier pigeon to complete final assembly.
Some advice for others: 1. You have to remove quite a bit of metal from the bearing adapters to get the inner wheel bearing to slip over. A little sanding drum on the Dremel and emery cloth got everything put together nicely.
2. An 1 1/8" socket makes the perfect driver for knocking outer bearing race out of the Volare rotors.
Other than that, things are progressing well. My calipers came in today and they fit the bracket perfectly. I'll load 'em up with pads and sit on the porch waiting for my washers. Then we can finish assembly.
I don't want to jinx it, but I'm actually starting to think it may all fit together.

So to try and wrap this up, I got everything together today:
Everything fit in place, which eliminated all doubt (to me) that my bearing adapters were fully seated. The B-1195 spindle washers that I got on Ebay were a little to big to allow the dust caps to seat in the spindle, but a little customization with a grinder made everything work out.
I guess my only lingering question at this point is how tight to go on the spindle nut. Instructions really don't give any info. How much bearing preload should I put on these wheel bearings? I'm guessing the right answer is "some, but not too much" but I don't have a good feel for it. Any advice?
Great kit, recommend it to anyone. Remember, if you're going with the 5 on 4.5 kit for 48-56 remember the part # for the seals is incorrect. Part # is 9406S not 94065. If there's any questions I'll do my best to answer them.

It is a feel thing. I usually tighten it until it starts loading up the bearing (the rotor will have some drag when you start to rotate it) and back off one cotter pin slot on the nut. Then I make sure I have no play by pulling the rotor back and forth and also make sure the rotor spins freely, if the rotor has "drag", it is too tight, if the rotor moves when you pull or push against it, it is too loose.
