I see, well then you have to make a flange from 3 bolts to 4 bolts like I did. If you look at my first picture look at the spacer between my manifold and throttle. You'll need to make a flange that bolts to the 3 bolts of the manifold and on the opposite side of the flange put 4 studs(symmetrical to the throttle) in which you will bolt the new throttle. Wish I had the pictures of the flange so I can show you, but its pretty easy and I can to help you out with questions If you are going to do that.

I know it's a bit late to get measurements off of the one you just installed, but if you could find a way to get the dimensions of the head-end flange holes, that would be great. If someone has a spare 4-bolt TB handy and could do the same for the manifold-side of the 4-bolt TB, that would also be great. I was thinking that you might be able to do a rubbing with a piece of paper and a crayon or pencil, or just trace around the edges and holes. I'm not entirely sure how you would transfer the image to the interwebs, but a scanner or something could be used. Hell, maybe even snail mail?

Edit:

I just picked up a manifold yesterday, and ordered a TB last night. The only thing I need to get this project rolling is the dimensions and layout of the cylinder head flange. Do you by chance know if the cylinder spacing is the same on the 1NZ and the 1ZZ?
