I have felt that front "box" would be subjected to the same abuse the rear member recieves from centerline floor jack lifting.
I don't know if it does given there are fewer reasons to lift the front end, but that is one area I would like reinforced during rebuild so it could be
That's a great idea. I find the front easily gets as much lifting as the rear. The problem is, unlike the rear plate, it's much harder to get in there even with a super low floor jack.
In that area I removed my tie down tabs and set it up for removable eye bolts.

OK, the decision has been made - it's going FIA racing !! The Cage is from Sassa in Italy and fully FIA certified.
was the roll cage expensive?
Is there any holes on the plate under the radiator that water can drain out through original?
I discovered a lot of "crap" on my car when I took it apart.
I'll make drain holes on mine. I begin with sheet metal work hopefully this weekend...

it is a lot of crap

no wonder it rusts

Anders, the roll cage was 550 euro incl tax but excl shipping. Shipping was around 150 euro to denmark.
Most of us concerned about chassis rust drill 1/2" OD holes in the extreme bottom of both legs of the 'horse-shoe' stamping that supports the A-arms as well as 3 more in each main rear frame rail. Drilling the chin piece below the radiator is a good idea, but due to the shape of this piece and the 2 degree nose-down rake recommended, the hole placements needed is not at the back but about half-way forward in the curved area. Leaking OEM thermostats and hoses have ruined many of these parts (now reproduced by Johnny Woods in England).
Removing the damaged support pieces.
These extra bars were actually added by Ford/detomaso after the first crash tests by ford - to protect against frontal impact and get the chassis to pass the impact tests. They are not present in the original design and fx #1267 does not have them. Thought about leaving them out for minor weight savings since they have no structural purpose in terms of chassis rigidity. In the end I left them there but did them in the thinnest sheet that I had.

I enjoy watching your progress and approach. Nicely done - please keep sharing.
I was thinking holes in the box would look good, but be a lot of work...but I guess a "lot of work" is not a problem!
are they punched or cut?

JFB, I'm not sure what box you mean, but yes, in the front, the factory Gr4s had holes stamped in the upper curved crossmember and the lower radiater support for fatique strength (and a little weight savings).
I thought about replicating this, however, since the structures are closed now, holes cannot be pressed/punched to create the edge thickening that is important for strength.
Drilling holes and then bending the hole edge may be possible using heat and a taper tool, maybe? Haven't figured out how.
