Wilson Manifolds 80mm throttle body
Ford style square flange
Comes with TPS, gasket and throttle cable
Has a hargett clamp flange welded on it but can be cut off or replaced easily
I ask because 86 to 93 cars all have them. The brackets for the throttle and cruise are setup for that spacer to be present. It is also where the EGR is housed (if still equipped).
