got a buddy bringing his nova down for me to put a 2x3 back half in with the tin work.when he drops it off he's going to want a round about price.i know i may have to modify the tubes from the main hoop to the rear of the car.this is going to be a ten sec. car.i'm thinking around $2800 parts included not counting rear end mods.does this sound like a fair price?just don't want to screw anybody including myself! thanks
