Need rear brake drums!

i found some chinese part number here and ordered them from Summit, it is the replacement for the helmet drums on the 790 340 Swinger. Summit keeps contacting me telling me they arent in stock and do I want to wait etc. i think youll find them but it may take a while for them to arrive...

If they’re a replacement the for the bell drums they’re 5x4”, not 5x4.5”, and they’re 10x1.75”.

The OP has a ‘74 with front disks, that’s a 5x4.5” bolt pattern car with 10x2.5” drums.
