Going to call General Spring in KC, I would like to tell them exact Ford part numbers for both front and rear. Thanks for any help.

Assuming it's not a Crew Cab and it's a 1976 F250 4WD (not the 1978 or 1979 F250 4WD in your signature):

 

OK, Ford parts catalog says:
Front springs
76-77 F250 Regular cab 4WD before S/N Y20,001
6 Leaves, avg. cap 1550 lbs (R or L)
D7TZ-5310-AD

6 Leaves, avg. cap 1775 lbs (R or L)
D7TZ-5310-AC

Rear Springs
73-77 F250 before S/N Y20,001 w/o Aux spring
6 leaves C7TZ-5360-F
9 leaves C7TZ-5360-G

Auxiliary spring (add to rear spring pack)
1 leaf C9TZ-5588-A

 

4 minutes before you responded, I posted the parts catalog pics of the front (except Crew Cab) and rear springs...to save you or I the trouble of typing the part numbers.

But I wonder if the OP really wants High Boy springs, as they won't fit his 1978 or 1979 F250 4WD's.

 

Yeah, while you were posting I was looking up the P/N's. I use the "bible method" for typing....seek and ye shall find.
I was going on the basis of the OP's thread title.

 

Thanks for all the help! For some reason I cannot edit my signature? Anyway I have a '76 and early '77 both F-250's I have added to the collection.
