Broke a trailing arm...

[Gumby'sC20]

Hey guys,

as the title states, last night I broke a trailing arm in half completely. I have attached a picture to show where it has broken. My truck is a coil rear 3/4 ton, don't know if it makes a difference (at time of install of a new arm it will) but thought I'd mention it.




I need suggestions on where to find a new arm (if the junkyard is suggested, which trucks can I find an arm off of that will work?), and will also need help with the procedure of installing the new arm with basic tools and a floor jack or two (haven't been lucky enough to get any tools yet).

Thanks in advance !!
