used the control arms from this for my new k member. you should be able to use the stock control arms you will just need to get spring perches to mount on the k member for the stock springs.
Actually I have a UPR C/O kit sitting in my shed. I'll have to check if they mount to Edelbrock struts. If I can make your K member work with what I have I may get this from you. And the good part is that I am about an hour from Baltimore. No shipping!
