Freak,
You should check out FTE.com (Ford truck enthusiast) lots of good info more up to date crowd not the "sticks in the mud", I have had lots of 67-72 highboys lookin at your pics I kinda think you have an F-100 that was converted to 8 lug. Thats why your rear springs dont fit the U bolts/block, the front hipinion is a bolt in from a 77-79 then the 8 lug stuff bolts on up, the rear D60 also bolts in except for the difference in spring pack width from 1/2 to 3/4 ton and the U joints. These things are like Yotas sooo tough and soooo easy to wrench on, you've got a great start there, any?'s ask away, good luck!
