started by staring at where i thought good lines would be at. then took a 2x4 block and put it on the gas lid opening and Whacked it pretty hard 3-4 times trying to keep it all nice and level. taking care so one side wouldn't be lower then the other.yup, a man's gotta have somewhere to sit and ponder and where better than lookin at your project !
I chose a. btw, i like it. How did you do that ?
