our front Dana60 spring perches bolted right up. basically the reason why our 74 frame swap. width is a big issue centering the wheels in the fenders, we're lifted and stick out.
that hump your going to have to deal with on your height at the floor.
the frame humps up after the cabour suburban just stayed above it and cleared at the tranny hump.
you can think about doing something like this [pic]; before you do your floor if needed.
box the floor laterbut know when to stop, when good enough is enough.
I know Greg <when you have some time, you might take a look thru his build thread and maybe learn from one of my friends; when is "enough"? At least take away, that life goes on and the Garage project is just a project. be flexible, adapt to the changes and don't be held to a due date.
