Power steering box

[gysgtc]

I just got my power steering box from Advance auto parts online. I ordered one for a 75 pickup. The one I received from them has a longer pitman arm shaft (it still fits) and the rag joint shaft is a lot bigger. The fittings for the hoses also do not look like they are for flared type. The part number on their web site is SG17501. I had bought the new rag joint a few days ago from one of their local stores P/N 200 and it is too small to fit on the shaft. It is a 3.5 turn box. I am running a serpentine belt setup so the fittings probably wouldn't be a problem. Should I use this box and get a different rag joint or try and get the right box? Thanks.
Nothing ever seems to go right for me on this build!
