correct distributor for 69 gtx

Could someone tell me the correct distributor for my 69 gtx 440 4 speed part number name brand and picture would be appreciate. thanks

Here is what I could find.

Tag information:
Mopar 2875772 or replacement unit 2875773
Prestolite IBS-4014B

It should be a black cast Iron dual point distributor with vacuum advance.

The vacuum advance unit should be a little long and have a threaded hex nut end with a nipple on it.

This is the distributor that is on my '69 4-speed (3.54 Dana) GTX......sorry I can't see the last number of the part number but it's the original I'm pretty sure and from what I could see (but not photograph) it appeared to be a 72.
