Anybody know where I can buy a replacement gaskets for a Holley 58mm Throttlebody (Model #112-507).Thanks

 

try www.lingenfelter.com they have always had them in stock when I have ordered.

 

Instead of trying to locate 58mm gaskets...I just make my own using the original as a template. Set your old one over the top of a standard 48mm gasket and pencil it out. Then cut it out with an exacto. Takes about 5 minutes and you dont have to wait for shipping.

 

Thanks for the info.
