Sure it'll work IF you use the proper bellhousing and bracket. It says for 67-69 models because big blocks were only available in a-bodies those years.

That's not the way I would go, though. If you don't want to fab your own go to Brewer's or Passon and check their stuff out. Paddock, Year One, etc. are NOT manufacturers, they are retailers. Most anything any one of them has can be found elsewhere for less.
