Great old truck. I restored I 6' step side. I have a great time with it. As far as the problem. If the problem started when you replaced the light assembly, there has to be a short in there. Have you checked the light sockets to make sure nothing is touching?
The odd part about this problem is that it takes 20 minutes to blow a fuse. A short should do it right away. Make sure you check the wiring behind the light assembly to see if there are any problems there. Make sure the lights have a good ground too.
