Yeah same here.. But just my luck I was one of them that had to take some off.. And in order to do that, I had to remove the tail housing. No big deal. Just those bolts hold it on..I got lucky and my gasket was intact. I used some tape around the shaft to get a straight line and used a wiz wheel to slice it off, then used a grinder lightly to bevel the edge..Not too bad

I don't know about your 78. But I have AC in mine and might plan to go intercooled down the line. The only problem that I see people talking about is the clearance behind the grill for the intercooler. With OUT ac they say you can do it. But with it, might not be possible..I haven't looked too deep into it though

The only thing I had to do with the fuel tank was put a fitting in for the return. I drained my tank, removed it, and blew air in it to evaporate the gas and dry it out.. Then I was able to clean out any dirt or anything in there. That and removed the sender to get access into the tank. I had to obviously remove the metal shavings from drilling the hole for the return fitting. I used my wet dry vac to suck everything clean. I then just ran rubber fuel line following my supply line back to the tank. Pretty easy..

I didnt have to do anything to it. I dont have a restricter in it. Back in the 70s when vehicles used leaded gas,the nozzle was as big as a diesel nozzle almost. After a certain year they made the fill tube smaller or had you install a restrictor,so you couldnt put a leaded gas nozzle in an unleaded vehicle. MINE has the full size hole in my fill tube. So the diesel nozzle fits right in with out a problem. Just look in yours and see If you have the whole opening in the tube,or a small hole for the gas pumps.
