48 Chevy 3100 Reassembly Questions

[buildinga55]

I picked up my 48 Chevy Pickup last week and started working on it. I will be disassembling the truck. The previous owner disassembled and put back together in pretty decent fashion. The doors, fenders etc line up pretty well. However, he just threw the hood on at the last minute so we could transport. The hood does line up nicely in the front and matches the fenders, but probably has a 3/4" gap at the cowl area. I would like to get things lined up before I disassemble to paint and work on the chassis. When reassembling the pickup, should I start with the hood and get the gap at the cowl nice then go with inner fenders, fenders etc. Or what is the best plan? Thanks
