Looking for good interconnects for narrowly spaced jacks

I just had my old Dual 1229Q professionally restored.  The RCA jacks internally are spaced about 3/8" from center of the jack to the other.  The smallest RCA jacks I have seen on quality RCA interconnects require jacks spaced about 1/2" apart.  Does anyone know of any that are small enough for this application?  Not looking for megabuck interconnects, just decent shielded ones.  I am not looking to change out the RCA jacks on the Dual.  Thanks!
