Well the project has just taken a real turn....

This might help.
HEMI DART K FRAME
I have one of Al’s Debevics k frames. Just like the one pictured in this link, it comes with mounts and brackets ready to go in. I believe the steering box mount is also moved slightly moving the box closer to the rail. It’s set up to use TTI headers. ...I could take pics but I suggest buying one. Your also most likely going to need to modify the right side Fenderwell/shock tower.
Hemi in A body modifications to fenderwells?
