2nd gen minivan dashboard in 1st gen?

Hey guys, I really love the look of the 94-95 minivan dashboards. I would love to swap one into my 1990 minivan. I want to convert to the 92-95 electronics as well. I have a spare 92 TI SBEC-II ECU. The reason for wanting to go with the 92+ wiring and electronics, is because I'd also want to have the digital cluster in there, which requires having a BCM and a premium one no less. I already have the minivan digital cluster, as well as a bunch of two and six button travelers I'd love to graft in, plus I want the fancy traveler overhead console.

What I am not certain of, is whether the physical mounting points between the two dashes are the same. Once I unbolt the old dash, does the 94-95 dash bolt right in? I know the old dash is comprised of a few large parts: top section, bottom section, metal structural skeleton. If I remove all the components from a junkyard minivan, will they bolt in?

A few things that I'm aware of and could use clarifying:

1. 91+ steering column needs 91+ rack (or does it?)

2. No 92+ turbo engine bay harnesses. I would love to have the newer relay/fuse box. Is my best option to find a 92+ 2.5L minivan and convert it's harness to turbo? Add a few extra pins to the SBEC connector?
