6 lug rallys???

[70K10Hunter]

Alright what the %#@&*?%^$ is going on here I just got a set of 6 lug rallys 15x8s. I took them out of the box to do a test fit on my front 4wd hub and the thing wont even go over the spindle assy what gives? the front end came off of my 70 K10 it is a D44 with disc brakes I am not sure of the year but understand that it has to be at least a 71 for the disc brakes. The center of the wheels is too small. I really wanted to use the rallys because I like the look.???
