seasand77 Posted February 6, 2003 Share Posted February 6, 2003 I need a replacement or rebuilt stock differential to include the ring and pinion. I've been told the Cutlass will not work, but that every big GM car that year used the same rear end. Impala, Catalina, Buick, etc. Is this true? Rocket raider says the Cutlass will work, but my local chapter president says it will not. I'm confused. Link to comment Share on other sites More sharing options...
rocketraider Posted February 7, 2003 Share Posted February 7, 2003 Re-reading my original reply, I see where I have confused you. The Cutlass axle will not bolt into a Delta 88 drum-to-drum. It's the gearset and carrier section that is the same between Cutlass and 2-barrel Delta.You still need to measure the punkin to see which rear end you have. Then you can narrow your options.If you're looking to replace it drum-to-drum, you should be able to use any 71-76 GM big car axle except one from a wagon. The Chevy might have the light duty axle. The C-body cars (98, Electra, Caddy) will have big brakes. Link to comment Share on other sites More sharing options...
