Short cables for Preout/main in and passive use

I am looking for a set of short ~6” RCA interconnects for use as pre out/main in jumpers and also to connect a passive pre to a Dynaco ST-70 amp I am having restored. Any suggestions?  I currently own several 0.5 meter cables that I can use for this but would like to use shorter ones if possible. Thanks in advance!
Nordost makes jumpers that are very good sonically.  
Sorry, was thinking of speaker jumpers.  
Audioquest and others make 6" pre-amp jumper cables. A google search of audio jumper cables led me to TheCableCompany. They had the AudioQuest jumpers listed. Give them a call or try AudioAdvisor if you don't have a local store that may carry them. 
I have used cables from AQ and Discovery for this. Many manufacturers do not advertise these but do have them if you call.
Cut the cables you have to 6 inches and re-terminate them!
You can use these if you don't want to solder!
Yogiboy, yes I have considered this. I do have several cables I could shorten. Can’t help but think there are those factory made for this purpose however. I want to buy used. 

good quality ones rarely come up used
