Hi Ash,
Again, congratulations, the car looks cool!
In regards to the problem of the Shaker Scoop not sitting correctly, I haven't gone back and looked at all of the previous post's, however here are somethings you may want look at...
1. Check to see if the rear gear box mount bracket and rubber are as per the original spec?
2. What's the tail shaft angle look like going along the lines of the transmission tunnel to the back of the vehicle (check to see how the rear pinion angle looks)?
3. Check to see underneath if the Shaker's bottom base (air cleaner) has not been cut down to allow the fitment of the Edelbrock manifold? Make sure it looks parallel...
Cheers,
Trans-Am:cool:
