I have seen most either using a late '40s Chevy truck axle and springs, or something aftermarket like Speedway. Is there any advantage/disadvantage to using the axle from a '57 truck? The reason I ask is that I will be doing an IFS swap onto one for a customer in the near future, and I can probably get his old setup for free. If there is something wrong with this setup (granted, I haven't measured it yet), I'll go another route, but if it will work well the price recommends it! I did a serach, but couldn't find anything specific. Thanks!
