Hey Torks97,
It's Torx T-50 for the seat belts.
For spare parts: "Say Hello To My Little Friend(s)"
Check out your local junk yard.
Ford wanted $176 for the weatherstripping around ONE rear cargo door. I got the weatherstripping for BOTH the rear doors from the bottom van pictured above. Cost $20.
One of the best things about a Ford van is how the parts stay the same from year to year. My van is a 1999. The donor van is 2006.
There is one downside. I passed on the drivers side kick panel from the top van, It might have been coffee or it might have been chocolate but I'm pretty sure what was on it was blood.
