From that picture, it looks like yours is an OE Harrison unit. Can you tell me what the part number on the top tank is? That'll help me to locate one. Then I just have to find a shroud! Or get a detailed drawing and try to build my own. I'm wondering if there is an HD fan that supposed to go with this setup as well? Stock fan for the smaller trucks is a four blade 18" fan. What are you running on yours. I like that truck, btw. Thanks for the reply.
