I used the monogram F-250 for the rear springs,rear axle and engine. I used the monogram bronco for the front axle, trans, transfer case and tires. the bell housing came from a johan torino stock car.
front springs came from a odd kit, it was the revell bronco with race boat. I built that truck about 17 years ago, before the kids came along. I remember spending 5 or 6 months planning and collecting
the parts that I wanted before starting it. Seems like I had more time and money back then.
