In need of a engine measurment

Ok i got some actual measurements for you, though unfortunately not from a barracuda.

My ‘64 valiant (engine out) has 5 1/2” from the steering link to the firewall, and 11” from the link to the flange where the firewall meets the tunnel.

My ‘72 scamp has 5” from the steering link to the transmission. Hope this helps.

That a big help. I found 1 picture of my original K-Member in the car. That puts the picture in perspective. There is no way to continue my build with out a mustang steering rack in-front of the center line of the wheels. We will see where this takes me. Thanks ~ John
