I suppose you came in on the end of a conversation with someone else. My original ra-20 axle gave up, and I tried to source the parts to repair it but no luck. I decided to use a Dana 70hd. I have better choices of gearing, and I got rid of the old bud wheels. Now, I have Chevy 8 bolt with a 3.73 gear. Some guys trailer there trucks everywhere I drive mine.
