quick question

i read a lot about people putting aluminum drive shafts in their cars. the question is my gta has an aluminum drive shaft and it come that way. i know this because it was a one owner car and the guy was 95 when he died. the car has never been touched before i bought it. so should this car have a steel shaft or did gta's come with aluminum. just wondering and have no plans on changing it.

some third gens came with aluminium shafts, some got them as a replacement from the factory for customer vibration complaints

Re: quick question

Check your RPO codes. I believe the code is JG1 for the aluminum ds.
