TTI 1 7/8 Race Header Install help

The sliptube takes a bunch of finese to get in.
From what i remember(it was along time since i installed those headers) install the complete header except the #7 sliptube and drop the engine into position then push the sliptube into its position before turning the flange in towards the head so to speak,what made it difficult is that you need to make that tube slip straight together,any angle in the connection and it will get stuck wish is correct if it was a loose fit it would leak a bunch.
Then again this is from a 10 year old memory... and as usual here comes the disclaimer,these cars are absolutly terrible when it comes to tolerances what works on one car may not work on the next.
