231-->242

[mjtjnj]

Hey guys-

 

Long time, no see. Now that it's getting warm(er), time to think about the summer projects. I have to do the heater core, rebuilt an AMC20 I found, and have the valve stems replaced :wall: .

 

Anyways, I found a 21 spline np242 for sale cheap - needs a rebuilt. My 231 is noisy and soon to be the ONLY drivetrain component that's not new(er)/rebuilt.

 

Is it a straightforward replacement? Other than the shifter plate change, will I have to mess with the linkage or the driveshafts? I'd rather get the 242, have it rebuilt, and then do a one day swap and not have too much downside, rather than taking out my 231 and waiting for it to come back.

 

Pro's? Any con's?

 

Thanks

Tom

Why not just rebuild the 231? I see a lot of kits on the web for around $125. Very easy to work on and there are plenty of "upgrades" available like stronger shafts, low range gears, SYE, etc...
