I made a pattern of the contour of the subframe, marked the centerline point & marked the F-100 frame where to cut.

To late to turn back now.

You need to unhook the steering box and lay it to the side. Unbolt the upper A-arms and lower the frame & check the fit.

Raise it back up and grind a little clearance. You might have to do this several times.

Starting to come together a little bit.

Alignment might be a little off.

After welding inside & out, I use 1/4" steel plate to box the frame in.

Welded in place.

I like to cut gusset plates to box in the upper A-arm mounts.
