Yup as
@threewood said lines and brakes and anything on the firewall first. Insulation heater box and all that stuff. Its kinda like working from the firewall out towards both ends of the car. After the lines and all that then the basic rear and front systems to get the car rolling and then you can jump on all the panels being mounted back on the car with the hood being last usually to give ya some extra room to work around the engine bay and such. Dash, headliner, and that all back in the car and plugged into the main harness and then you can do the rest of the interior, glass and weather stripping and any other pieces. I'd save the trim front and rear and whatever other trim for last or close to it. oh and black out the front core support now before anything gets bolted onto the front so its much easier.
