Re: couple questions regarding options on my car...
RPO J42 is the aluminum drums, RPO JG1 is the aluminum driveshaft, as for your axle, its likely a 10 bolt but all you gotta do is count the bolts on the rear axle housing.You might be lucky and have a Dana 44 that someone added...

'88 seems to be a year GM put a lot of aluminum driveshafts in the cars as stock equipment. After that they get rare. But it was optional, not standard. I'm 99% sure you have a 10-bolt, and it has 3.08 gears.
