NOS 1970 Door locks trade for 71's

I have two NOS 1970 door lock repair kits which are uncoded. They include the stainless pieces. Group 10.550 #3981843. Will only trade for NOS 1971 set which carries part #3901066. They are made for specific keys. The 70 set fits key letter J which I think also fits 1974. 71 key is A. I only wish to trade on these not sell. I may decide to use a used 71 set and rob the stainless from this set as a last resort. I know more people are restoring 70's out there so here is your chance for the real thing and not Chineseum junk.

 

These sets are enough to do both doors. I would need two 71 locks as well for straight up trade.
