69 C10 SB Build
 

Hello everyone, I am building my 1st truck ever. It's a 1969 C10 Short Bed. I have attached pics. I am am looking for a little help from you experts with a couple parts I need. So far we removed an old crate motor and replaced with brand new 350 small block. Also added new everything for most of the components. I appreciate any feedback.
I need to replace the fan and clutch, I need some kind of block out kit for the holes in firewall where I removed the old broken AC and looking for ideas and places to find this type of stuff. Also any suggestions moving forward would help.
