Sorry. I modified my SU-22CA to make it an SU-22C. I measured it before and after and the unfolded lengths were close for the C and CA configurations, but I was waiting for someone with an SU-22CA to chime in. KTOG is usually the sort of place where there would be 2-3 answers cross posted in the first three minutes.
For what it's worth, for my SU-22C (not the initial factory configured SU-22CA):
I'd guess that the folded length of the SU-22CA would be about 2" shorter than my SU-22C.
