" The top has already been cut, 7/8 on A pillar,3/16-0 on B sail panel,, do you think it looks out of proportoin now ?? Most will never think it's cut "
The roof line on these cars stock is all wrong, the front is higher than the back. What you are doing makes a huge difference in look of the car.
I like the proportions of the Venom glass bodies,they made me realize how bad the stock roof was. Check out Jesse Greenings site, he's doing one also.
