Hi all,

I am currently replacing my tired 253 with a 355. Everyone suggests I might need to worry about my diff. Its currently a GU4 (3.04?) behind a Trumatic.

What should I upgrade to other than a ridiculously expensive 9"

I'm not looking to race / drag or burnout (too old for that)

Just need to be sure it can withstand the 355

Appreciate your thoughts
