I have a 2003 clk 430 that needs a new hood. I found a 1999 e series hood for a good price and it looks like the exact same hood as the one my clk has. Are they the same hood? And would it fit on my c

Looks like it will fit

Unfortunately, while all the front end parts look very similar, the CLK- class parts are smaller than the E-class front end parts, thus they are NOT interchangeable. Hope this helps.

I doubt that it will work. E class body is a bigger. I have a 08 CLK cabriolet. My friend has 2011 E class. The body is definitely bigger.

Measure it. Open the hood, back, from side to side. Middle, rear to front middle. Front side to side. middle, side to side. Must be exact. If you found it at a junk yard, they have access to parts nation wide. Have them look for one. Look at the price of getting a used one vs. having a car repair place fix what is damaged. Do a comparison, and the painting should be a wash in the pricing. Chances are, the car repair place will get a used one anyway as MBZ may not have one in stock.
