I bought a 1999 4 door blazer last April and it did not have a jack cover. I know I could go ask around at scrapyards but I'd rather just order offline. Does anyone know any good sites for this and will other model years fit?

 

There is an eBay store devoted to Blazers and S10s. They can sometimes be pricey but only place I know where to buy online without going OEM new. The one listed for $13 is for 2-doors and the $45 one is the one with the cargo shade (which I like) but with shipping its $60. All depends on what your budget is.

I find it more rewarding myself to go to a Pick-N-Pull or You Wrench It style junk yard and hunt down the piece. And I'm SURE it would be much cheaper.

Either way, Good Luck!

Oh, and it doesn't hurt to email the guy running the eBay store. Sometimes they'll keep an eye out for the piece you need.

 

Or watch on here and craigslist or wherever else for part outs.
