67/68 barracuda dash interchange.

I researched this out and am fairly familiar with the little differences. ( Speedo cable hookup, etc. ,etc.,)
Found a guy here with a 1967 complete dash (metal dash, dash pad ,cluster,pot metal bucket, circuit boards, switches, radio, wiring, everything) for a decent price.
I am considering buying it to improve my 68.
What I want to know , (since my dash cluster, gauges , etc., are so trashed) , is if I could just put all this into a 68 Barracuda metal dash. or would I need to swap out the metal dash as well?
As I recall you need to pull the windshield to swap metal dash. yes?
PS, please redirect if this is a thread somewhere, I looked but couldn't find it.
thanks
