On my 2001 blazer my driver side door is hanging low and was wondering where I can order new pins to hold the door in place. Thank you.

 

most part stores carry the bushing pin kit - I bought my last one at orileys

 

X2 for O'reillys. That's where I bought my pin kit. Although, if the holes are to worn out, the door might still sag.

Still can't figure out why GM decided it was a good idea to weld on the hinges...

Like was mentioned, most parts houses have the rebuild kit of the pin and the bushings.

I had a door where the pin had eaten through the bushing and into the hinge itself.
Luckily, the new bushing still fit without rattling around, there was just a section of the hinge that normally traps the bushing that was missing now. Once I had it all installed but still had the weight of the door held up by a floor jack, I used some of that 2 part steel epoxy that comes as a stick where you cut off what you need and just knead it together to make it cure. Then it was just a matter of packing it into the void so the bushing once again had support in that area and didn't get torn up again too easily.
