Good source for front end kit for '70 dart?

Years ago I did a stock rebuild on a granny '67 Dart front end using a PST kit. The idler arm went tits up within a few months, called PST to warranty it. They were absolute d*cks-the slant 6 suspension in '67 had the bayonnet-style, 1-year only design (which I paid the extra charge for). They wouldn't stand behind their product, then told me they didn't have it in stock anyways and wouldn't be available until more got produced. I was forced to order one through "Rare Parts" and got hit for $94.99; since then I swore to never use them again and warn anybody who will listen to go elsewhere. PST sucks!
