This sucks!

Ummmmm..........yeah....
So I decided to follow some of your advise and put the manifold on and move it back and forth to make markings to identify the points of contact an the underside and... it went right on!!!! Yesterday it was wobbly and had about a 1/4- 1/2 " gap all the way around the manifold, today it fits. I didn't do anything different to it.... have no idea what changed... must've been some newbie mistake. I dunno.. Thanks again for the quick replies to my problem, I appreciate the expertise of all of you guys on this forum!\\:D/
