i think i need a gear reducer for my 67 camaro it has a p/g i put in a 160 speed but it reads way too fast does anyone have a reducer to sell or some other way to fix this? thanks kenny

If it read too fast before here is a link that will help you select the correct gears for your application:http://www.novaresource.org/

I don't know what the problem would be if it was from the speedometer change.
