Newbie - Need Hard top.

[71 Blazer NC]

Picked up a blazer recently within the last month and new to the forum. Have seen some awesome builds and picked up some good information fumbling through the site.

Not sure if this is the right place to post, but I am looking for a single wall hard top that is in good to great condition. I have one but there is no hatch, windows, and some cracking in the fiberglass. Hoping to find one near North Carolina. Do any of you know a good parts guy in this region or where I might locate one?

Also, noticed a little rust on the rear cross member above the tires. Looking to replace this but couldn't find a match of what I am looking for on LMC. Is this an easy part to find?

Thanks everyone in advance for the comments. I look forward to looking at some more awesome builds and pictures.
