Beltech drop spindles

[oddjob197500]

hello,

I have beltech drop spindles on my 68 c-10 with a 71 front disc brakes. I called beltch and they advised that they do not make a drop spindle for my year truck. How different are the 71-72 spindles from the 73 and up ????????I believe the beltech drop spindles part number starts with 31 and something else. I cant remember the rest right now. I bought the spindles a few years ago, i just installed the ccp tubular upper and lower control arms. I am having steering problems and the spindles look like they dont line completly up . I did have the same spindles on the stock upper and lower control arms in the past with no problems?????? Any help would be great.
