K member

I’m going to be putting a built 400 bb in the car it was originally a slant 6 car and shumacher is taking forever to get the conversion mounts I need in so I figured it would be best to just upgrade my k member? And I seen this but didn’t see my year listed. Will it still work for my 1975 dart

What about Mancini racing
