As you know the Excursions never came with manual transfer cases. They were all electric shift on the fly. I'm going with a manual - how hard could it be?
After we pull the seat out and pull the carpet back we see there is a cover plate to accommodate the xfr case shifter in the Super Duty trucks. In the Excursion there is a heat duct that blows air from under the driver's seat to the rear passengers.
You're gonna have to tough it out if you sit behind me. No floor heat for you! I cut the duct off to access the cover plate.
Then remove the cover plate and cleanup the body sealer.
I sealed up the duct with aluminum HVAC tape and reinforced it with gorilla tape. Also opened a hole in the under-body insulation.
Next we test fit the shifter. Hmmmmmm Looks to be too far back.
For whatever reason, the transmission and transfer case sits about 2" further back in my 7.3 Excursion than in the V10 gas Donor. I had to shorten the rear driveshaft by 2" because of this. It also appears the shifter sits further back than in the Super Duty trucks. Hmmmmm.
So we'll re-install half the cover plate so the boot will have something to screw into and we'll trim the floor a bit behind the shifter. This pic is with the shifter in 2wd - all the way forward.
Haven't trimmed it yet - lunch break. More to come!
