Question TBSS intake ?

Have a genuine TBSS intake that's going on the L33 in the 55.
Have the original bolts from the L33, but they are too short.
Anyone know if there's a different part # for the TBSS?

Do you still have the L33 intake manifold? Compare the depth of the bolt holes between it (or any cathedral truck intake) and the TBSS unit.

My 02 Sub has the intake on it. I'm going to pull a bolt from it and do a compare.

Thanks

Got it figured out....
My bad. Trying to put a round peg in a triangle shaped hole.
Seems the holes were not cleaned out when the part was molded and finished.
All 10 holes have a weird triangle shape at the top.
A close look at other intakes on the bag show clearly that the holes are round.
Time to fire up the Uni-bit and finish the job..
I guess it having the GM pt number is a bit misleading. Ho Chi C-h-i-n-k got me.
