Mine was super easy, with my neighbors help. But there was nothing to get in my way under it, no heater/ac box, radio, wiper system, glove box, etc.. The other day I described my latest plan revision on my car as it being like a go-cart, just basic needs first., brakes, steering and propulsion. All other stuff will be added later as needed. In the future I may get one of those little simple add-on hot-rod heaters to keep from having to go thru all the bs with rebuilding and installing the stock one, not to mention the weight. There is so much room under the dash now I could put one under there that could not be seen very easy.
Well it's been 5 years today since I started this thread and it's starting to be a new years tradition for me to count the passing years, a tradition I'd like to end!, or finish the car anyway. My new year's resolution is to get it running this summer.
Happy New Year 2018 everyone!
