Glad to write my first post , my name is Mike and Iam the proud owner of a 1970 olds cutlass convertible . At this time it is spread though the garage and back shed till the reassembly begins . I've lifted the body off and am in the process of stripping down this chassis . I have a low mileage lt1 that will be fitted into it with the 4l60e trans. Kind of a retro mod project.my question is about the o type rear in the car ,I would like to run a higher gear sinse I have a overdrive. Parts for this rear seem to be hard to come by and the only aftermarket one I found is pricey .should I look for another rear ? Would like to put tougher the one I have but not sure what my options are , Iam sure u guys have some great ideas appreciate any input . Iam sure you've heard this question before.

 

Welcome to the forum! Sounds as if you have a real project ahead, we all are looking forward to seeing the pics with the first mods.

 

Welcome to the site. Post the details of your rear in the drivetrain section with your question and suggestions will follow.
