Need 1969 Chevelle KK and KQ 410 posi rearends

[L78M22Rag]

Need the following rearends - for two original (no clones) 69 Chevelles:
"KK" coded 410 posi dated prior to my L89 Chevelle's 05C build date; and
"KQ" coded 410 HD posi dated prior to my COPO Chevelle's 07D build date.

Please respond by PM. Any help would REALLY be appreciated...

I have a very early KQ 0225B rearend (early for COPO Chevelles) that I would trade for a later dated KQ rearend (better suited for my car). Once I find a better dated rearend, this early KQ really ought to be re-united with one of the early Yenko Chevelles....
Thanks!
