Not sure how much on the chop as I got the car with it already done. After looking at the rest of these photos I’d guess somewhere in the 3-4’ range.
Mine with 3" chop and doors flush fit doors. Put together, blow apart, put together, blow apart... finally finishing the frame for the last time !! Front end is done and installed now, finishing rear end then the complete frame/suspension will be done ! Then back to body.
