Just for laughs, here is an NOS 2809013 piece (72 date code) with a vintage Anco copy alongside.

Here is a pair of nipples to check out. Same pumps, different view.

I have about a dozen more variations of wiring, plastic color, canister shape etc.

Does your head hurt yet?

Excellent photos and informative discussion.

Does anyone have an engineering drawing that shows the washer bottle and electric pump? I have seen a few drawings that show the manual foot pump setup, but not the electric.

I am hoping that I won't have to find a nonexistent NOS side exit pump for my Oct 69 SPD Cuda.

ALL 70-71 I have seen in junkyards and orig cars had the side exit as do both of my 71 e-and b-body. I have never seen a correct NEW/NOS or reproduction pump. I guess the one year only thing is the reason why. This is one of those reproduction parts that nobody makes....Yet.

I have a decent amount of NOS side exit Anco washer pumps if you guys need one. It has the single hot wire prong with the attached riveted ground wire like the original. Feel free to email me at lidsville@comcast.net if you are interested. I will post some pics of one. Dave

So, on the two pumps I posted with part number 2771975, does anyone have any insight on why they have the same part number but different applications?

So, knowing the caliber of restoration professionals/hobbyists on this thread, my question is:
Who's going to be first to reproduce the correct pump and offer it?
I just started the stop watch...

Excellent research and documentation guys.

Just stumbled across this older thread and decided to go check my NOS washer pump I have on my Cuda.It points down towards the frame rail and has part #2771975-3019 and date code? 0120 burned into the tab.On the end of the metal pump hosung is McCord C-4169.Any new info?

Jim - I stumbled onto this unicorn pump a couple of years ago. Part number 3431295 stamped on the pump. I'm having a tough time reading the date code but I think it is 1120. Vendor code 44037B. Part number 3431599 on the box. McCord housing number - C-4169.
