axles

when i had my little accident (spun and broke my drivers side rear rim) i thought thats all i did. turns out that i bent the axle too!
now i was talking to a guy who has rebuilt like 100 f bodies over the years and he said that because i am going to be doing some modding that i should upgrade the axles.
the housing is fine. he said try moser. any one have any suggestions or thoughts to help me out.
thanks
