I was wondering if there was a parts store in New Jersey that would have aluminum AST in stock I didn't want to wait for shipping. But if I can't find locally where should I buy one and any brand preference.

 

Nipple broke on the stock AST on Sunday afternoon, car had to be running on Wednesday, ordered on line from RX-7 Store Sunday night, overnight shipment, replaced part Tuesday night, on track Wednesday morning. the whole process took less time than finding an AST localy, cost a bit more most likely though.

The racing section in homedepot might be able to help you, or
Just do the ast delete, cheaper and less stuff to worry about. most mazda parts dept's will have it in stock

 

the stock one on my car was just replaced. the stock one was in good condition before replacing. im in union county.
