The small-block stands were also used in the '73-'79 trucks with 351M/400 engines and will work just fine for swapping a small-block into an earlier truck.

The perches need to be from a 2wd truck .. Is your truck 2wd or 4wd ?
About the crossmember
About the crossmember
IMPORTANT: There's a rumor floating around that Ford redesigned the front crossmember for the '77½ through '79 2WD trucks, which also meant the engine perches had to be redesigned, so these trucks couldn't be used as engine perch donors for earlier trucks. However, while there were redesigns on stands in '77½, it wasn't due to a change in the crossmember. (In fact, '79 6-cylinder trucks use a D4TZ (left) and a C5TZ (right) stand. That means one stand never changed from inception!) The '79 trucks use a D6TZ-5019-B frame front crossmember which is also the replacement for '73-'78 and fits all F100/F150/F250 and F350 2WD with Twin I-beams.

The '79 trucks use a D6TZ-5019-B frame front crossmember which is also the replacement for '73-'78 and fits all F100/F150/F250 and F350 2WD with Twin I-beams.

instead of the I-6/FE ones I have.SAME engine supports (aka towers/stands perches): 1969/79 F100 302 / 1975/79 F150 302 / 1977/79 F100/350 351M/400 2WD

redroad: 1977 1/2 only refers to F250 4WD's. The last High Boy was assembled before serial number Y20,001, the first non High Boy was assembled from serial number Y20,001.
This serial number occurred in February 1977, which is the middle (77 1/2 or 77.5) of the model year run.
Engine sizes have nothing to do with front cross members. Plus, Ford is in-famous for replacing/updating 10's of 1000's of part numbers EVERY
YEAR!D6TZ-5019-B (replaced C5TZ-5019-A) .. Front Cross Member: 1965/79 F100/250 2WD / 1975/79 F150 2WD / 1976/79 F350.
C7TZ-5019-B .. Front Cross Member: 1967/76 F250 4WD; 1977 F250 4WD before serial number Y20,001.
