Suburban wheelbase?

[1971 cheburban]

Was the suburban a 133" wheelbase or 127" like a long bed. Reason I'm asking is my truck frame was cut and notched like you do to a LWB to make a SWB, and a suburban frame was cut and notched and welded to it, so now it has a heavy A$$ set of leaf springs and a 12 bolt. But a body shop did the work and thought they had the wheel base off but it's actually dead nuts on at 127", so my question is a suburban wheelbase longer than 127" and in turn have a longer driveshaft or is it not, the body shop thought they had it off but it's actually perfect, and they had all of the suburban parts at hand, so was it a case of mistaken driveshaft length or just not checking the driveshaft, also the longhorn or camper special has a longer driveshaft and wouldn't fit either, they may have had one of them also
