So I am curious :confused: about the possibility of making custom torque boxes and wanted feedback or if anyone else has done this.

I have had my new floor, cowls, and rail work done and it is nice and clean with no torque boxes installed yet. I was thinking about making a torque box, well not really a box, but using tube steel or square steel stock and welding together a custom made frame that will go in place of a torque box but would be welded in all the same stress points. I just think it would be cleaner, no chance of future rusting out, and stronger.

Any ideas?

More than one way to Skin A Cat !! Its purpose is to prevent torsional stress,....twisting. My '67 has only one,...on the drivers side, it's not twisted after 45 years. I would think some well engineered subframe connectors,....not what they are selling out there. IMO current connectors on the market, from a structural fabricators point,....make little sense, especially at the front connection with the floor pan stiffening support:bloated:. Take a look at this example;http://www.google.com/imgres?q=mustang+subframe+connectors&hl=en&client=firefox-a&sa=X&rls=org.mozilla:en-US:official&channel=np&biw=1024&bih=635&tbm=isch&prmd=imvns&tbnid=q7QocgRWJzmhqM:&imgrefurl=http://www.allfordmustangs.com/forums/1213755-post21.html&docid=tokVtPBpuarr_M&imgurl=http://www.allfordmustangs.com/forums/attachments/5-0l-tech/53788d1224262770-what-exactly-do-subframe-connectors-do-do-they-really-make-difference-mvc-008s.jpg&w=640&h=480&ei=KK2gT43xDYfO2AXxre2sCQ&zoom=1&iact=hc&vpx=411&vpy=328&dur=427&hovh=194&hovw=259&tx=127&ty=210&sig=115306429047641586388&page=2&tbnh=136&tbnw=181&start=15&ndsp=19&ved=1t:429,r:6,s:15,i:122 very elaborate, but the rear is connected at only one point to the rear frame rail and then,... to the floor pan support in the front WT#? At a minimum two points of connection to the rear frame rail and a heavy connection to the front frame rail, not the floor pan support, with a torsional brace near the engine. Then needed would be a couple tie points through the pan,....preferably at pan strength points,..like at the back of the seat riser and then the floor pan support. Can find little logic in current subframe connectors design!

That is sort of the thing I was thinking of and I already have the front to rear frame rail connectors.

Sorry I am not a good artist on the computer and not sure if my picture makes sense but kind of like this idea with tube round stock steel of square.
