So I wanted to give every one and update on this saga I recieved a new bolt and spacer from PST but they were both still to long which was my error it was hard to get a good length on what I needed. I went to the local hardware store and purchased a 6 " bolt and cut the spacer to 3 " and then every thing fit. Thank you to PST for trying to help it's appreciated. To any one who's thinking of buying after market sway bars or for that matter any after market parts for you 73-74 Charger do some research before buying get your measurements and then talk to the supplier to make sure there parts are the same as your factory parts it will save you alot of time.
I installed mine complete the other day and don't see any clearance issues as far as going to the bump stop I would think you would have to hit a huge hole to max your suspension out to hit the rubber stop but that's my opinion I can give you and up date once I drive it some. You don't have your strut rod connected to your LCA so I don't know how you can get and accurate account of it hitting every thing is under a load once every thing is together it's hard to say when there's no weight on the parts your putting together.
So I was able to get aligned and I was driving it around but I was hearing a noise when I would hit bumps guess what the question you asked about the brackets hitting a K frame . Well I've got witness marks on each side telling me it is because I repainted the k fame before I installed every thing .
