Help evaluating hard top please.

[patmcd44]

Newbie to this board in the process of purchasing a 1971 Blazer 4x4. Everything about the truck is pretty straight forward for me to evaluate with the exception of the top. It has a large ugly patch where the previous owner installed and then removed a 12" x 12" vent. He said he put the original piece that he cut out back in the hole and used fiberglass bondo to complete the patch. He said he didn't care what it looked like so he never spent any time sanding it. Also the hatch has some cracks and ugly bondo as well. I'm looking for opinions if this is easily repairable or I should be searching for a new top. I imagine this is the first of many questions I will have with my build! Thank you for your help!
