Who is making a good A/C manifold for early 400's ? I've recently bought two off evilbay and the first one was listed for the wrong year and wouldn't fit the accumulator and the second one fits but my garden hose is thicker than the hose they used to make up this one. The low pressure hose kinked flat when I tried to loop it back to the accumulator and I can pinch the high side flat with my fingers. It's the Four Seasons brand name but definitely not the quality of their products I have used in the past.
