Oddly enough I kinda knew this but was skeptical. But it makes sense since GM went all out in the 80’s with TBI until they realized that MPFI was the better route.
MoPar still has a bunch. I finally got my five in today at work. They come in black rather than that tan and the part number is 6504995AA. I’ll get a picture in the morn on those if you would like. Or use the part number as cross reference.
