Moser vs Strange

The main reason im asking is i got a 8.75 out of a 79 D100 worlock??? truck, axles and the center section for free. I plan on sending it to moser to have them cut it down for $125 (i think) and I saw that moser had a spool and axle package.

Another question is... Should I get the truck axles cut down? (heard that they were beefier and stronger) or should I just buy a packaged deal?
