Welcome to the show!!! Also just down the road in SA , the heart of the Shuswap. Very nice Dart. What shows was it in? How did it do? Will be following your build.
360 in 1967 a-body? Don't think that could be original. But engine swaps are not that frowned upon. Looks good in picture and stored inside is always good.
If your going resto and not stock , hit the wrecker for seats with built in belts. Then you can have it all. leather,power,heated, and belts. Small size caddy are good donors I read.
