The Ford Vans from the early '70s into the late '80s (I think) used mostly Dana 60s. There are lots of different brake and wheel options. The stock 1T and 3/4T "small 8" lug pattern is exactly the same as GM and Dodge of the period. The stock sizes are 16.5 X 6,7,8 and 16 X 7, 8 for the plain-jane wheels. Most were 4.11 and 4.56. The 4.11s were found behind the 300 L6 and SBFs. The 4.56s were behind both sixes and SBFs and in both 3/4 and 1T.
Around here in Central NC, the small time stock car guys sucked up every Dana 60 they could find, and the 4X4 guys aren't far behind, so those are hard to find. I hope this helps!
best Wishes,
