My understanding is the housing is even thinner than the G body 7.5". Auto cars can last but stick cars die quicker. Either way good luck with the rest of it. My BIL had a 95 Camaro Z28, nice car but he found out the oil pick up had fallen off the motor, a common problem on the LT motors. He made the dealer adjust the valves due to a tick and found out this happened to the previous owner. Then of course the mighty 4L60E gave up the ghost, it got rebuilt with a bunch of upgrades. It does suck dealing with previous owners abuse and GM's penny pinching on these cars. Andnother reason I avoid them, most were bagged to hell and unlike most G bodies had enough power to break every piece of the drive train. Good luck and drive Pontiac's last kick at the 🐈.
