I have used the taller spindles AND the offset bushings together on many builds and there was never a problem with the alignment. But stock spindles and stock UCA bushings often will not come in.
Talking about this!
Locally all mopars have REALLY bad reputation about front end weakness and aligment troubles. So bad, that ppl tends to remove the stock K frame and modify everything needed to install CHEBBY subframes down stock frame rails ( usually 70s Novas &/or small Malibus on A bodies at least )
Some ppl however use to cut the UCA and elongate them by an inch or so get them outer just right an offset bushing.
Some ppl have changed the LCA bushing using brass pieces or even BEARINGS on them due premature failures. I have think this deal is related to oil leaks on engine which damages the rubber &/or tighten up the LCA pivot nut before set the ride height, breaking the bushing out when seting the ride height after tight the nut.
Whatever, the question on this is, if have somebody found some problem on frame rails being bent or twisted after all these years causing the aligment issues being the UCA attached to frame rail? Meaning this due the offset bushing existance and now you mention having a similar problem.
Need to say locally Mopars have allways abused after all these years. And has being like that since ever!
Once again sorry the highjack, but since has being floated out somehow, maybe is time to ask
