If my memory serves me, I remember working on a mid 60s early 70s econoline with 6 cyl and 4 speed shift on tree. Just a memory jog from your post.

Are those long cast iron manifolds or shorties? I had no idea they would fit 57/8/9s Impressive. Looks like you have done the 58 steering swap.
Yes. a 58 box was installed, and they are 406 shorty manifolds.
Kugel Components is now reproducing the Ford Shortys.....They are beautiful.
