Changing to Doug's D453s

I got them on my 71 dart that was a /6 conversion with the mounts, power steering, 340/727. I have a manual valve body so I can't comment on it they would work with the linkage. Lots of room up top for changing plugs, really tight underneath for the starter (have to use a mini starter) and one header has to be loose to install the transmission. I also have another set I used in mock up on a 72 duster with a 4 speed. They fit that application too. I'll get you a couple pic's if you want them.
