I'm currently in the process of installing a B16a1st Gen into my 91' CRX Si...

Before i start going crazy with changing items i had a question about the Intermediate shaft...

The axles i got with my package were well... not in the best of shape, and from a post i had read earlier i know that you can switch up the Axles with integra axles as long as you change the intermediate/half shaft.

My question is firstly...

I did a search for this but want to be sure... Is #21 the correct part if you need to change the shaft to have a good fit. Also how difficult would an install like this be, i've never actually changed one before.

I'm also wondering if there is a more cost effective way to do this, or if i should just buy a set of axles online. Any tips would be great.
