Not sure the number but if one has let me know. Shop to 02081 Ma
Here is a parts company and what they post. FYI

 

The correct pump is P/N 231066. Note that this is the part number on the box, not the casting number. The casting number is 408329. This is a 5.6" tall pump. Note that this pump was only used on 71-72 W30 motors without A/C and also on 1971-72 full size cars without A/C or without Y72 cooling. Good luck.

The link is for a 328 pump, as Joe said he is needing a 329. The 328 is 5" tall, 329 is 5.5". The 329 is also identified by a large 2 cast at top left of pump. The 328 should have a 1 cast in same location. Be aware that I have seen a 329 pump that is 5" tall. If OP is not worried about an original they are available aftermarket. Just make sure of height and hose size are correct BEFORE bolting on. A 70 WP is different than a 71.

Additionally, the waterpump in the eBay listing did not have pictures of the impellor, nor did it include 2 nipples, which is something to be aware of when you do locate the correct waterpump.

Hope this helps...

Edit: Well, I take that back about the 2 nipples; some photos show 2 nipples others don't, go figure.

Just kidding, it says pay now, receive never...
One image does not even have holes for hose outlets...
seems to be a rash of this sort of thing here...
Where's ointment ?

 

My original water pump from my ‘71 non-A/C 3:42 W30 has the 408328 pump and it has an “X” where the 1970 “X” is. I’ll try and post a pic also of the pump since it’s off the car for a rebuild.
