Body shaming
Appreciate your passion but TCI is one of the best street rod chassis builders in the country. Not the cheapest. Before I purchased their product I visited their facility, now 32,000 square feet, and talked with the GM as I toured!
There are a number of ways to build a quality rear suspension (by the way my front suspension is double wishbone adjustable coilovers with sway bar and have disk brakes in all 4 corners.
Yep would be perfect to have a Watt's linkage to keep the rear perfectly centered (better than any arrangement of a single Panhard rod BUT not much room in a tubbed chassis!
Have a number of text books on chassis design and use Chris Alston's book on setting up an adjustable 4 bar link rear. Bit of math with instant center calculations, identifying the CG etc. But then I like math!
Below is from the TCI (Total Cost Involved.) website. They have built thousands of street rod chassis and mine has run just fine for 18 years! In fact they were a help in supplying hi res pics for the book I wrote for CarTech Pro series in 2015 (on advanced welding.) Great folks, great products.
"In 1974, Total Cost Involved Engineering began to set the standard for quality when we built one of the first Model ‘A’ reproduction frame. It took the Classic Car restoration market by storm. Today, we own 32,000 square foot manufacturing facility, where we deliver a broad mix of products serving Street Rodders, Hot Rodders, Pickups and Muscle Car enthusiasts nationwide. We’ve earned numerous design awards, including the coveted ‘Manufacturer of the Year’ Award from SEMA-SRMA. Through a well-trained team of experienced engineers and machinists, we’re still setting the highest standard for reliability and performance, as we’ve done now since 1974. We promise to achieve this standard in all the products we deliver to you. We take quality very seriously which is why we offer a 6 Year/60,000 Mile warranty on wear & tear items and a lifetime warranty on any part we manufacture in house. Quality doesn’t cost, it pays."
PS: Know all about "lawyers for injured people!" I consult as an expert witness (for insurance companies etc!) The last case paid for my Grand Sport and a current "wrongful death case" will pay for my C8!

Perhaps your design is fine, but sure hope it is better than your welds! Talk about a disaster!
