Best Upper a arms for 72 a body

I used the POL disk brake kit from performanceonline.com with their upper control arms, haven’t aligned it yet. Only driving around the neighborhood. Went together nice. Only complaint so far is the ball joint dust cover doesn’t sit right in the carrier. It’s off by a small fraction. I’m going to take them off and hit it with my cartridge roll and make them fit right to keep the dust and moisture off the ball joint. 3A5EB91C-EFC6-4003-96FE-5FB0C717DEEB.jpeg36FDC94F-2649-4E6C-8CD7-A679172E7DCB.jpeg
