For the tranny, it is from a 77 model of something from the D7. What is the engine size?

7006 = Ford casting basic number off the trans case.

D7UP = 1977 Econoline.

If the trans pan has 11 bolt holes: C4 / If 17 bolt holes: C6.

Some 1977 300 I-6 Econolines came w/a C4, some came w/a C6. 351W/460: C6 only.

But, 1977 Econolines were not available w/a 302. 300 I-6, 351W/460 only.

Since I cannot cross the casting number over to a part number, it's possible this same trans was used in 1978, the first year since 1974 that a 302 was available in an Econoline.
