That's the fun part of fabbing from scratch and not using store bought kits.l

If it needs shortened, relocate mounts, shorten tierods. If widened, add a piece, relocate rack mounts and stretch the tierods.

Measure the overall width as it is now. (Outside of tire to outside of tire.) Is it too wide or too narrow for the Falcon? It should be in the ballpark.

If the width is good, fabricate the rails to fit the crossmember, not the other way around.

You can buy longer or shorter tie rod ends. You can also cut and re-thread the tie rods if they are too long.
The frame rail modification is the way to go.

I ran into another lesson while finishing a previously owned, stalled project. Make sure you can adjust your caster and camber sufficiently BEFORE you weld everything on permanently. Keep your upper ball-joint slightly behind the lower one.
Keep on tinkering.

Ok, got this figured out. Found a company that sells the blueprints for the M 2 crossmember with detailed installation and set up instructions, 16 bucks. I’ll build my own. Something that just occurred to me though, after the shock towers are cut out and plated, what is done with the export brace ? That thing is important, right ?

Depends on your structural plan. If you're building a full frame, it becomes "body on frame" and the braces are no longer required.

If you're grafting the MII, the body is the frame and the braces are critical. If that's the idea, you should fabricate/relocate the export brace. A "Monte Carlo brace" would be a wise addition as well.

For example...



Before I flap my lips any more... what is your plan?

My plan is to remove the shock towers and suspension mounts, steering box and column and install a M2 front suspension, a slightly warmed over 302 backed by a 5-spd with a narrowed 8.8 posi rear with 3:25 gears. Also an Ididit steering column.

No subframe connectors?

Hadn’t thought about it really, I’ve never seen a set that actually looked like they might contribute anything more than marginal stiffness to the body. If I would make a set, they’d have a flange on both sides for the full length and be spot welded every inch and a half or so
