One of the members here, His handle is 3B, found mine for me at Rockauto. Mine is a 1957 - 2 & 1/2 Ton GMC COE. It has 4 springs per wheel on the rear. The price was good too. All 8 of mine were broken when I bought it. I have yet not been able to navigtate Rockauto site, but he found them. They came all 8 in a box for 15.39 Wtih shipping only cost $26 for 8. Part # H500
NAPA # is UP80164 cost $17.10 not including shipping.
Of course this info is for a 57 GMC, yours may be a different part #. But this will give you somewhere to start.
P.S. They may move this topic to the driveline forum.
