Lil Pixie, the 57 build

[Carryallnuts]

Hello,
Don't mean to barge in but I am trying to do the same mod. 57 3200 with a 75 nova sub frame. I want to make sure that I am doing the right thing and would like to confirm the correct place of frame surgery.
I am trying to make mine look like yours, going by the pictures and my own measurements.
Just to be sure and to validate my figures: Can you give me the distance from the body mount to the top of the frame, where the downward cut starts.
Thank you very much for any help you can give me.
Ken
