I saw your post and I did a little work on my end. I checked and we use TRW part #'s for our kits and the upper ball joint that we supply in our kit FEKPGDOD732 is TRW# 10162 which crosses to the moog part# K772. So the answer to your question is no. The K704 is not the upper ball joint in that kit. But so you do have additional info. The K704 crosses over to a 10164 in the TRW book. If you have any questions please let me know.
Thanks
