I'm in the process of trying to get my A/C working on my '71. It still has the old York dinosaur which will be replaced with a rotary type. I'm sticking with R-12. Although I'd like the condensor up front, I'm going to wait on that project.Question is: Has anyone replaced the stock with the 4 row condensor? And if so, was there any difference in the cold air coming out. I'm aware of the draft theory at 50 mph. I'm in Houston, TX and any comments would be greatly appreciated. I'll also be replacing all hoses and the dryer, so hopefully it will work somewhat good. Which brings me to another question. I have to replace one of the hoses going up front because it's chaffed and you can start to see the steel braid. Since I'm running one hose I might as well run the other one. Is it as bad as they say it is? Has anyone had to rerun these?
