I done all of the above after enthusiasm from Colin
I didn't bother with the alignment pins. I would buy new bolts mind as you may have problems getting the old ones out and they won't be reusable.
I bought the subframe/chassis bolts from Ford then had then zinc plated.
The others I sizes up and got them from my local fastener place £££'s cheaper.
I done the steering rack/arms etc whilst the whole thing was on the floor, then popped along to have the wheels re aligned, job done.
Then the next week I done the back axle
