Dilemma on body part installation

[larey]

So I have my 1980 C10, and when I purchased it the hood had the folding option, so I dropped a few bucks and got a new hood, and both fenders. Finally got them primered and ready to put on, but my left inner fender and the radiator support are rusted and should be replaced. So should I go ahead and mount the fenders and hood till I can afford the other options, or wait.

To give you the background the truck does drive, but I am in the process of rebuilding the step side bed. I do not consider the truck reliable as when I got it the rear shocks where loose in the mounts and other items needed more attention.

The hood I will more then likely put on as without it the engine is open to the elements, but what about the fenders as the way it looks it will be easier to put it all together at the same time. I am not real sure what else lies beneath except the radiator support and inner fender as the rest looks solid. I also have new hood hinges to put on as well, but did not get the springs.

Thanks for the input,

Larey
