I'd be that friend.
FJ60/62 front axles are 58.5 WMS to WMS. If you can find one that isn't as rusty as the one I have it's an awesome axle.
Cruisers use a wider leaf spring so the spring perches will not work with mini leaf springs. You'll need to replace the spring perches no matter what, plus the 60/62 axles are SUA.
