'72 scamp ?

I have the same car, and if you dig into the tears on the drivers seat, you should find the build sheet....I paid 3k for mine and have done a bit of work on it...the one you are looking is great for the price.....I wouldn't let a little rust scare you, but definitely screen the body with a magnet checking for heavy bondo work...I didn't and later found a motorcycle had hit mine in a rear quarter, 3 inches of bondo surprise....
hit me up and I can walk you through fixing your grill for around a $30....budget...
it is a simple fix..
