I am a ford Parts manager and have been helping some of the guuys on here out.
I can't tell you the specs, but I can give you pricing on what is on the van.
Caliper kits with the seals, boots are $19.82 each side (Genuine Ford, not fake OEM)
If you want the slides, sleeves for them and boots, these are $13.85 each your cost.
Let me know if you need me to send them to you.
Been in the biz for 30 years and am trying the internet thing to help people, if I can.
