Big ron,
I did almost the almost the same thing with my 69 datsun 2000 roadster. Had a winter coat with a hood on the passenger seat under the tonneau cover if it got really cold and an umbrella if it was raining and I had to stop at a light. That got me some strange looks. The windsheild rake on that car keep all rain off me if I was going at least 10 mph. The xfire still gets you wet at low speeds. The datsun top took about 5-8 minutes to put up or take down. It was real tinker toy affair. I admit in akron Ohio, I finally put the top up around Xmas and put in back down in March. but it was one quick car with no traction from it's toyo hard as rock and this as a model t's tires. I think it had about 135 HP but it didn't weigh anything. two shifts and you were doing 90 in 3rd.
