In the process of converting my 1989 Firebird with the 5.0 TBI to a Quadrajet and HEI setup and was wondering if I can reuse the stock tv cable bracket with Quadrajet carburetor?

If you are sticking to a q-jet the factory q-jet TV cable bracket will work but not the TBI bracket. There are other options out there, consider Bow Tie Overdrive https://www.bowtieoverdrives.com/col...ems-tv-systems if you want something more adjustable. If you ever change to a different style carb and are forced to replace the bracket I highly recommend these.
