Michael, thanks for the overlay graphic. It clear that the 2013+ calipers don't fit the earlier axles, so short of changing out the knuckles an upgrade doesn't work. I'll look to get a1:3.73 ratio 2016 axle assembly since they didn't come with 4.10's. I will only be running running 33-34" tires and will have to decide which is best ratio to switch to. The ambulance is a 6.0L diesel. Any thoughts on an appropriate ratio?
3.31 and 3.55 were the most common ratios in F-series trucks. I'd try to find the best deal on a '16 with one of those ratios and plan to change gearing. 4.10s or 4.30s would probably be close...would have to run the numbers through a calculator.

I bought a 2008 4.10 front axle on car-part.com with 43K kilometers
Here's a pic of the recipient vehicle leaving the Montreal area yesterday. The pickup was delayed over a week because of bad weather.
Yes, it is a DRW front axle and I expect to keep the rear duallies, at least initially. May go to a rear SRW 10.5" later. I'm chewing on what to do about wheels and wheel bolt patterns. On my last Van I converted the stock rear axle lug bolt pattern from 8x6.5" to 8x170mm using quality adapters. I don't know yet if this is advisable or even possible on a heavy ambulance with duallies.
