I am trying to plan the next step.

...I have to remove the lower bracket of the transmission crossmember (red arrow)—this will make room for the rear shackle mount. I’ll think about a different type of lower support to replace the original, because I think the trans crossmember will remain in the same place when I drop a Small Block V8 in to replace the Inline 6, while using a similar 4 speed trans.

...I will be cutting out a section of the frame to remove the curved out emergency brake frame attachment (red square) which is in the way of the mount. The replacement steel will come from the 3/4 ton “Blue Ox” frame, which will have the factory hole (and flat steel) that the grade 8 bolt will pass through, holding the shackle. I’ll take better pictures the next chance I get.

...I think this will do it.
