I will not be swapping crossmembers for the front suspension/ motor mounts as I just found a serious crack forming near a very rusty area. The good news is that I found it is not going to be very hard to transfer the pivot brackets off of the f250 onto the 2wd 150. I was able to get one of them installed before I ran out of time today. I hoping to have the dana 50 ttb 8 lug front end pivots and beams installed by the end of the night Monday then the real fun of making the coil and radius arms work starts. It is going to involve a bit more fabrication for that part.
Just for your information just installing the f250 pivot brackets compared to the f150 original pivot location provides about a 3" drop for the pivot points. This in my case is a good thing because I am looking to lift the truck about 4 inches from the low factory f150 2wd stance.
