Hello, I am building a 1972 bronco from scratch. I have finished the engine (a 1972 302 bored out to a 347) and have bought a refurbished frame. Along with this frame I have bought new axles (Dana 44 and Ford 9 in), as well as a 5.5 inch suspension kit. I have schematics for this whole chassis assembly, however these schematics do not have bolt sizes or lengths. Specifically, do y'all know the specific bolt for the rear engine mounting bracket?
