Why shorten the hitch?
Looks like it should set right on. Maybe cut the end pins short to clear the car's trim?
Maybe use the 1.25" hole-saw to cut access holes to make it easier to access the retaining pins?
Might be 10 pounds heavier this way, but might be quicker and cheaper?
Can you fit the roll-cage bars?
Cops won't trust hidden bracing, they'll need to see a cage before they'll let you continue on your way, when using these hitches.
It can't hurt to do a quick test-fit, to see if you're on to something. I'll do pics when I try it. Might be a day or 2.
What I like about shortening it is the idea of making it seem more like it was intended for this application.
'06 GMC C2500HD RCLB gasser 4.10:1, 4L80E, custom camshaft
'84 Trans Am 6.2 diesel, 700R-4, custom Class-3 receiver
'69 F350 dually. GM 6.2 diesel, turbo, 700R-4, NP208 all pending.
Just test-fitted a borrowed dually wheel. I hit 2 problems. First, the wheel hit the drum before I got it on, and second, even there I had about 1/2" of clearance. My figuring had some errors. Gotta go find them.
So with this axle, I can run single 215/65R16D tires rated to 2271 pounds each, or I can swap to the 10.5" 14-bolt. Spacers aren't legal in Utah, not that I'd use them.
I'm not eager to tackle another axle swap, nor am I eager to go dually, so I'll see how bad the available trailers squish a single pair of tires.
Lost my phone today. Pics as soon as I find it.
The combo hitch is "completed", painted and test-installed.
I'm SO itching to do a test-connect to the gooseneck! I may just jump the gun, strictly for motivation. Pics if I do.
Still no ideas for hiding the 7-wire connector at the rear.
I did have some ideas on some bolt-in connections between the 2 hitches, both inside and underneath. I gathered some steel for it.
But for test-hitching, I don't think I need any more bracing or reinforcing. I think I just need to do the new rear springs and the airbags inside the rear springs.
I can use the 5er as is, but there's no way to secure it in. I need to drill some access holes in it. I still want to cut it down. Not sure I can have it in with the hatch closed, unless I shorten it.
I'm feeling honored by 100 views of these pics, with no bashing.
I'm sorry my progress is slow, I do the best I can.
Still feeling no concern for the final weight of the car. Just missing driving it.
This project might make more sense to some people if I started with a 2012 Mustang GT, and a part of me hopes I get the chance once people see my results on youtube.
I really don't believe that any independent-rear-suspension can ever go with serious towing, and by serious I mean any trailer over maybe 2,000 pounds.
But remembering my old 300ZX, I can't help wondering what vehicle on earth has the strongest, beefiest, most massive IRS. Anyone know if the Ford Excursion 150 ever had it? Any others?
