So, I had a 91 buick regal UIM that I figured I would put on my bonneville while trying to fix the intake manifold leak and all the other problems that came with the "new" motor.
Anyways, unfortunately, it doesnt have the EGR, and I am a little confused about the vacuum. For the EGR, I am just going to drill the UIM and add a pipe and bung to attach an EGR tube. Vacuum..... I'm at a loss. I assume that there is some type of vacuum block that attaches to the square hole in the top.... Anyone verify that for me, or is that hole for something else. I just need to know whether I need to fabricate something, or if I can pick one up somewhere. If I can pick one up, any ideas where?
I coulda taken a picture of mine, but it is so much easier to just post a link to an e-bay auction that has the same thing. This is the style intake manifold I have: http://cgi.ebay.com/ebaymotors/91-92...Q5fAccessories
