I have the cover and the manifold, but does anyone know what else is needed to bolt it to the manifold. Would be easier if I had an SS in front of me.

 

If you already have the cover, the only other parts you should need are:
10272909 – Upper Cover Bolt (wing nut) (1 req.)
12601206 – Bracket (1 req.)
11609652 – Stud (1 req.)
11588711 – Bolt (for bracket) (2 req.)

Here are a few pictures of the TBSS cover as installed on my GMC Canyon.

 

Nice. Thank you brother. I guess I can order the parts through gmpartsgiant.

 

Here is a parts breakdown, but be aware that some parts come already attached to the others when you purchase them and makes ordering them seperately unnecessary, something I unfortunately done unknowingly.

 

This is what I grabbed per your instructions. Sitting in my cart.
