Or you could just start with the right truck and avoid all that work.

Last time i looked at a 92 f250 frame it was the same as mine and my frame has the holes in it where ford would have mounted the front leaf hangers with rivets but idk it could have been a f150 with a leaf spring front end 4wd setup i was looking at

i did a little digging and not to disprove you but i had a ford service tech tell me that the frames on the f-150 and larger up till 1997 had the same frame. He said that the differences between an 92 f150 and a 92 f250 is the rear and front axles brake system and suspension system the towing package for both the 150 and 250 are identical and most of the time included a external transmission cooler in front of the radiator (which i have already) that ties into the cooler built into the radiator. Ford did this so that they all can go down the same assembly line and get different options (which is why i can use items off a 150 4x4 of the same year) also the front ends are rated for the same weight rating theoretically you can take the springs and shackles off a ttb 250 axle and replace it with the coil mounts ans shock mounts with a little fabrication

Stop for a second and think about what you just wrote there, you're going to be building an F250 anyway so whay not just start with one and avoid all that work? There were light duty f250's back in the day that was only slightly higher capacity than the F150 and this is probably what your friend was alluding to, but you need a HD truck to tow 10k safely so something built on a 1/2 ton frame is an accident waiting to happen. I guarantee you the f250HD and F350 trucks had much bigger frames than the LD trucks, my father had one and the frame C channel was a full 3" taller.

That would be easier! If you have an extended cab short bed then you will have to look at late 90's F-250s because they were the only ones configured that way. If you have an extended cab long bed then you should have a lot of frames to choose from. If you are willing to make a trip out west the junkyards are filled with solid, rust-free frames that you could probably have for close to scrap value.
