the best axles i have ever used are http://www.raxles.com
they are all brand new parts and have a lifetime warranty
the set will run you $325ish shipped depending on where you are.
they hav all other applications too, but this is just my personal feeback on their hybrid axles.

 

here is what I am doing I am using the 90-91 integra axles and I am going to replace the intermediate shaft on my Y1 tranny with the 90-91 integra intemediate shaft..
get rid of the Sir parts and Bam!! the integra axles become a perfect fit...
We did this on my buddies DX and it fit up perfect he's running rally and drag with no issues

 

yup that works too. but you can get raxle 90-91 integra axles and shazaam...new axles that are very strong
