70 AAR Automatic Distributor

[SeventyTX9RTRag]

My distributor was replaced by a PO with a Mopar non points style distributor years ago. Would like to buy a dual point and put it all back stock. Have seen some 69's for sale and did not know the difference other than the metal tag. Is there anything I need to be aware of between a 69 and 70 dual point distributor for a 340?

Thanks guys
