[Kenwood] TM733A Detachacble Front Panel Kit

[W7SAC]

Hey gang I have friend who is looking for a DFK-4 or 7 (B or C, or no
letter?) Detachable Front Panel Kit for his TM733A dual bander radio.
Does any one have one they are not using at descent price. I have the
DFK-4C on my TM-V7, is there a difference between a C and B kit, I see
some listed in older catalogs with no letter designation at all. Thanks
and hope to hear from you'll all info submit is appreciated. 73 Mac
