You sure you was looking at the right post? Cause blitz hadn't posted any pics yet unless I missed them on another page.
Now that you've shown some pics that helps. When looking for parts you will need to let people know you've got a coupe (hatchback) and that's it's a square headlight 210. The round eye and square eye 210s are different in headlights, taillights and bumpers. At least in the States they are. You're front bumper is nice. Keep it! Can you show pics of your rear bumper? I'm not terribly familiar with how the Sunny bumpers look in other parts of the world. I come across 210s every now and again and might be able to get what you need. Does it look like this?
This is how the rear bumper looks on a round eye
You can find weatherstripping for the doors, at least, on ebay. I'm assuming that's what you mean by rubber kits. I haven't seen any for the quarter windows for the hatch but I think I've heard of some folks making their own gaskets. Something I need to look into myself. Ebay also has them for the front and back windshield. I've gotten the ones for the doors and they're ok. Could be better in my opinion. I haven't tried the ones for the windshields yet.
