I used the 73 Abody shumocker conversion mounts. Like a Dumbass I sold the car over 5 years a go. But if I remember right all I had to do was cut a inch off the top of the left side K frame engine mount and redrill a new hole. No other cutting that I can remember..I will look up the instructions and post them here. I massaged the seam in the firewall to trans tunnel. It took 3 people. One on each side holding the 2 inch TTI headers, but it took me less than a half hour installing the 440/ 727 into the dart. I used a summit Ford/ mopar 28x19 aluminum radiator. Number 2 and 4 spark plug. You can change from up to. But I used a 5/8 spark plug socket that you can use a wrench on. I used a 8 QT morose oil pan that came from a 66 plymouth B body . Other than that nothing special had to be done. Oops forgot had to cut a hole in my hood for the Tunnelram intake I was useing . I will try and post some pictures of my old car latter today
