i dont think the 4 bolt TB will work on your 3 bolt intake. if so then i learned something new. plus the TBSS tb is 87mm an the NNBS tb is 87mm the only 90mm is the car (vette, camaro, etc)

2008 GMC CCSB 6.2/6L80e swap
Gen IV 5.3/60e swap 1994 ecsb W/T
I misread it , I guess.
Thought it said TBSS intake on a 4.8 engine. The TBSS TB will work on a 2007+ NNBS 4.8L intake.
There is a company that makes a 4 to 3 bolt TB adapter just don't know what company it is though.
