Slant 6 6 into 1 JR/Mopar Performance Header

Based on Killer6's first hand observations and trying to make these headers fit on an early A (thanks Killer6) , they most suitable for a 67-76 slant as I initially thought. These do have the nuts welded on for the installation of the slant bridging washers and as he mentioned, the primary tubes are pretty big (I don't think they're as big as an OEM tailpipe, but pretty big never-the-less). I'll see if I can get some kind of measurement and update the thread.
