Mixing and Matching Steering Parts

I've had nothing but the worst luck with the aftermarket K frame I purchased so I reinstalling the stock one. It's a slant 6 k member for a 73 Duster that's hosting a 440. The problem that comes into play is this. I have 72 spindles with willwood dynalite brakes and they are for the 72 spindle. I measured to find that the 73 lower ball joint will not bolt up to this spindle. My question is this: will the 72 spindle work with the 73 steering linkage? The only thing I could see being different is where the tie rod end connects to the center linkage. The 72 is longer than a 73 and would cause the t.r.e. to be back a little and could cause less turning for the wheel. Any thoughts? All help is greatly appreciated.
