I am looking for a throttle body spacer for an 86 3.8L V6. All of the autoparts stores near me like baxters, schucks, autozone, napa, and carquest say it will have to be custom made. But I know they have to be out there because the 3.8L V6 has been around forever, and was in the grand nationals, so there must be a throttle body spacer. Any Ideas Names, numbers, websites to look for??? Any help is appreciated.
