What year TBs are the same size, and same bolt pattern?

The 99-01 are the Cable 78mm, with a 3 bolt, and the 02-09 DBW are 78mm with the same bolt pattern? Is this correct?

Thanks.

 

99-02 were all 3bolt 78mm drive by cable

03-07 were all 3bolt 78mm drive by wire

sometime after then they went to 90mm 4bolt drive by wire

 

THe 07 and up GMT900 body style have the 87 mm 4 bolt dbw and the tbss intake.

 

Now did the 07 and up GMT900 body style have the 87 mm 4 bolt dbw come on the 5.3 and 6.2?

Thanks.

 

Yes is it.

 

Thank you.

What are some after market Throttle bodies?

Thanks.

 

I think the TBSS intake is in and of itself. If my research is correct, all 07+ and even some pre-07 SSS and 3/4 ton 6.0's have the 87mm TB but only the TBSS has the cathedral L92 intake. My research has been wrong before though lol.
