Mac Header install and EGR crap! need help fast!

ok guys i got some mac mids, the install has been really easy so far, but i went to hook my egr valve crap back up, and that part you are suppost to screw in the header just slides right in! the fitting isnt big enough! so what do i do? i need the car done completly and ready to drive by friday morning! are all macs like this, or do i just got a bad set, or am i doing something wrong that should be completly obvious? i really need to get it figured out with in the next 1-2 hours, but dont see that happening! Could i just find a plug to plug the egr's on both sides? if so where at? thanks guys sorry for all the questions just really needing to get this done!

Sounds like you are talking about the AIR fittings.(The big tube on each side that's on primaries #1 and #2) I needed to get adaptors from Jet-Hot.

I'm not sure of the exact size you need, but if you call www.jet-hot.com and tell them your situation, they can help.

If it's truely the EGR fitting (back of the intake), the EGR tube slides into the #8 primary adaptor and then there is a metal flat bracket that has a screw which goes through it to clamp the two together.
