I'm just curious as to what vehicles would be a suitable donor for everything that I need to do the swap. Mine is a 75 D100 318 4spd with manual brakes and manual steering. I would like to eventually swap out the manual steering and the 4spd for PS and an automatic, and if everything was interchangeable, I'd even do the manual drum brake to power disc brake swap. For now, I'd like to tackle the PS swap. The pump and brackets, hoses and sector, and even the column (hopefully for an automatic) would all be changed along with the pitman arm, if needed. What vehicles and years are compatible, and am I overlooking anything on the swap? Also, would the frame on the D100 be predrilled for the PS gearbox?
