Everyone seems to compare at the 12 o'clock postion. I have the dynacorn tubs on a 69 camaro which measure at 10 o'clock 13.5" - 12 o'clock 14.5" - 2 o'clock 14". It looks in pictures that the DSE tubs cut into the frame rails more. Mine only goes about half way (the narrowest part of the frame is still 1" wide). This is where I think the main difference between the two are at the 10 o'clock position???
I'm curious what the DSE tubs measure in the different positions. If someone with a 69 camaro and DSE tubs could take a couple minutes to measure, then everyone will know the difference.
