71 Duster 360 turbo build
I now have my trigger wheel thanks to Subcom’s help. He provided the design file and I was able to have it cut locally for $25. Also procured some 3.23’s, but I’m hesitant to install them due to my converter already a bit loose with 3.91’s.
Fyi-I’ve seen 4.26 regularly used for the inner hole diameter on our cars; 4.31 is what mine needed.
