Try alonzo St. google map it. Its parallel Sabino Padilla St. (nee. Gandara). Alonzo intersects Aranque Market.

For more specific shop listings, try looking at the yellow pages under business and industries. Lots of entries there.

As for the Stainless grades. Look for at least grade 304 or grade 316.

Muffler shop probably gave you the lowest grade of stainless: grade 202 or maybe not even stainless which may explain premature rust.

Stainless steel - Wikipedia, the free encyclopedia . Look under "types of stainless steel" for more explanation on the different grades.

Thanks.
I see. but what is the difference of the 304 and 316?
