Trottle body and spacer

check yours again,,
i was measureing about 1'' or so up inside the bore,, not the actual end of the bore.
i noticed the bore on the end where the spacer mounts kinda tapers inward a little.

I measured mine at the end of the bore. I wanted it to be the same size as the throttle body/EGR spacer. It may be bigger past the end of the bore. I do have another upper sitting in the garage I can measure. It does look slightly larger beyond the . The most important thing is that the end of the bore is the same size as the throttle body/EGR spacer and not smaller.
