Sub-frame connectors... Please build them correctly!
Yup Yup Yup,
I have a 69' Cuda I built back in the 80's with a 440, this was before the mega information age and instant information access and I was also in my 20's. It had no subframe connectors and with slicks I started to see this drivers side rear roofline crease develop and get worse the more I raced. That's when I learned about subframe connectors and I ordered some bolt ins from Direct Connection followed the instructions (I think, lol) and drilled some holes, bolted them in and Bingo the roof creasing stopped, my 60' improved and the car stayed straighter when hazing the tires. THESE WERE NOT WELDED IN and they obviously made a difference. I certainly agree welded in and tied would be better sooooooo guess I will do that. Mopar packrat that I am I still have this Cuda but many others have joined my Plymouth portfolio (hahaha) since and the 69 just sits tucked away for now as my backhalved 64' Valiant is a better track setup. Interesting and informative thread but my personal experience with non welded and tied connectors kinda disproves your stated fact that it was a pointless endeavor. It's all good bro!
