The Frame mods were made for a couple of reasons. One was to make a mount for the main hoop of the roll cage. Also with all that torque, over 600 ft. lbs minimum, the four links that are put under load are right there as well.
The 5 link suspension took me 2 months to get. but they build these in batches of 5 or so, and depending on when you order, it could be 5 month I have been told. If I had to do it again, I would probably just make the suspension myself. It is pretty simple. I would probably use C4 or C5 outer bearing carriers, and just make up all the brackets.
In order to install the Guldstrand 5 link, you need to bolt their bracket to the existing trailing arm bolt hole. They then give you a couple of "lugs" that you are supposed to weld to the back of the frame. These pick up both the bracket and the lower links. It all makes sense when you have the parts in front of you. everything is located from the stock holes, so no real drawings are needed.
You must also cut clearance in the rear part of the frame so the upper link will fit in.
More trivial issues are how you anchor the emergency cable and brake lines.
Best bet is to weld a lug to the frame near the caliper and just put the SS
line there. Don't try to run the line up the links like stock, because it will be hard to adjust the arms with brake lines in the way.
The emergency cable is a bigger issue, because the stress of the cable jacket on the bracket is vital to making it work. Here I am making a bracket that will have a 1" dia. hole in it and a clamping ring on it so I can mount it to the suspension link and still loosen it to adjust the suspension.

The cross member was fabricated by me, and it has 4.5" diameter tobing to pass the 3" dia. exhaust through it. I made it removable so that I can swap the clutch and trans with the engine in. It seems easier this way. I have my Cobra set up the same and it works well. It took a couple of days to make it, but was pretty straight forward. The bigger issue was the interference with the floor. Between the transmission, the exhaust, the bigger drive shaft and the racing seats, the entire floor was cut out and re-made with fiberglass.

With the larger transmission and bellhousing, I could not use the stock gas pedal. So again, I just made one. It works a cable that is perfect for the 502 Ram Jet fuel injection system. It has a adjustable stop and is mounted to the stock firewall holes. I positioned it so that it would work well for heel and toe use.

Finally, I am in Florida, near Palm Beach. If you are near here, please call. I would love to show you the car. If you need any parts made, let me know, I might be able to help.

I have probably solved some of the problems that you have run into.

Somehow I let this thread slip by not noticing it. I'm going to use set of Brembo mono block brakes all around, gonne order the calipers first and fabricate the mounting brackets when the time is right. I really could use your expertise on the whole brake line/P-brakeline issues. I'm still planning of going the Guldstrand route, so I'm following your footsteps on this one. The gas pedal assembly is also something I'd love to get, I just ripped out the last pieces from the burned wreck and the gas pedal assembly looked nasty and twisted, so I'm gonna throw it away. I showed few of your pics to a frined of mine and he said it would be possible to machine the Guldstrand style brackets but he would need to get every single measurement to do that, so I think I'll be better of just calling Guldstrand and order a set.

I just finished welding the frame for now, made many triangle shaped pieces and welded them in every imaginable palce to make the frame more rigid and stronger.
