Proportioning valve or no for 65 Dart disc/drum brake conversion.

Yes, I’d like to keep the 5x4 rather than drop more cash on new wheels and tires too. This is the one I was thinking of getting. Comes with lower ball joints.

I'm "PRETTY" sure it's a rebranded MBM front conversion kit....

Most every retailer gets them from MBM I found in my exploration. (the images match across multiple sites). I went with a power conversion kit from Classicdiscbrakes in Texas and they drop-shipped from MBM in Asheville, NC
