Looking into putting a Richmond into a 4-spd E-body, car already has the 4-spd hump.

I have been told by one fellow that the Richmond + linkage all cleared his 4-spd '70 Cuda with no messaging necessary.

I did not see this with my own eyes, and have heard stories just the opposite, but I don't remember the details
and it might not have been an E-body.

Anyone have E-body experience with the Richmond ?
