Rear lift Spring ?

[FM5332FF]

i have a m1028 and i was taking it apart this afternoon to install a 12" lift, i figured that the rear leafs would be the ssame legnth as a regular 1 ton chevy which is 56" long eye to eye, but when i measured the springs that came off they are 64" eye to eye, have any of you lifted your m1028 using diferent rear leaf springs, if so where did you get them, i know a 88-98 chevy uses a 63" eye to eye leaf so i might go that way. any suggestions ?

Has someone modified the truck previously?

The M1028's got standard GM K30 packs of the era so they should be 56" long too.
