Classic auto air install 1970 Duster with 340 and Edebrock Super Victor EFI Manifold
Just had a look with the 3D printed tube my friend made for me, it was made in 2 pieces and glued together:
The idea is that it goes above the gage cluster. I am probably just going to double sided tape it to the dash frame. The gage cluster did fit in my case, but nothing in this car is original (gages, wiring, fuse block)
