Blanik parts help

We had a ground handling mishap and we will need to replace the final
section of the fuselage tail skin on our L-13. This is where the last
two bulkheads are and where the tail wheel assembly attaches. I´m
waiting for a reply from Blanik America but I have the impression that
this is a hard to find part. Any junked Blaniks out there getting
parted out?
Also, could someone with access to a parts catalog give me the part
number?
I imagine it must be fairly common for this area to get damaged as it
absorbs all the abuse from the tail skid/wheel. Ours already had a
small crack that had been patched.

Thanks,

Juan Carlos
