A X flow manifold will not fit the pinto, the spacing on the manifolds looks about right, for most of the weber carbs, but definitely the 36/36 DGA DGAV, so that includes the 38 DGAS, from a 3L V6, and also fits a 40DFI, if you can find one, as they are a bit rare but is the one to go for power wise, they were a performance option on the V6.
