Disc conv. and shackle flip all around on my 70 K20

[Former member Yoder213]

So I've been lying,

No D60

my model number says 44 56 and then I have some numbers stamped straight above the model number on the differential housing, all the diagrams I can find don't give me any relief in the double number or the number above the model number,

busting out the wire brush and getting the BOM

but has anyone seen this or other funny stuff regarding where numbers have been stamped? I've heard of them being under the bracket or over a foot away from the diff.
