Unleashed

So i recently went to the junkyard to pick up a engine for my buddies 2000 xj and i came upon a rear dana 44 on a xj which i ended up taking out for myself and i also came across a set of crossover Wj knuckles off a 2001 Wj i believe but i ended up taking them apart and buying them. What i did not realize is they do not fit 15" wheels and minimum size is . Right now my 15" steelies are brand new and so are my 35" kuhmos M/T'S and i do not know to keep the knuckles for future use because i know i am going to put a dana 44 up front which i know they work for but that is not for another couple of years or do i just sell them and find some later on?

oh and here are the knuckles i picked up
