Which Bijur pump for 1971 Bridgeport?

The mill has an old DropsA pump which needs repair, and parts are no longer available, so I've been looking at a Bijur pump. Here is a pic of the DropsA on the mill (minus the lube tank and actual pump mechanism)

The problem is that I'm coming up with two different models of Bijur for a Bridgeport.

Here is one:

D3174C - Bijur L5P-R One Shot Lubrication Pump

But Hardinge sells this one as an OEM.

I looked at the specs of both pumps and they both put out 75psi and both are 1-5cc shot.

Is there any advantage of one over the other?

I'm a little concerned the one with the lever will hit some hardware installed on the mill (when the knee travels upward).

Lastly, the one Hardinge shows has a splitter right on the pump itself. Any idea if that can be removed (since my mill already has the splitter attached to the knee)?
 
The picture on the H&W site is the Left hand version.
The lever points to the front on the R version and to the back on the L version.

The place yours is mounted is where the pump is normally placed. I moved mine (L5P-R) about a foot to the back and mounted it on the column out of the area where chips fall. It is connected with a nice loop of plastic line to allow the knee to go up and down.

If you get the unit from Hardinge, you will need a couple of Bijur plugs to plug the unused holes in the manifold attached to the pump. You need to find out if the manifold is inch (5/16-24) or metric (M8X1) threads.
Bijur markets a pump that looks like the Hardinge photo, the L5H-3 with inch threads. But they make a lot of custom units for the OEM's. It is best to verify the threads.

Just as a follow-up, I ended up ordering the pump from Hardinge. I called Bijur regarding the fittings required (Re: Bill mentioned above - SAE or metric). They didn't seem to know anything about it, and wanted over $300 for the same pump.

I suspect there is some metric to SAE adapter required. Hardinge recommends an adapter with the pump (which I also ordered) and the link JR posted on Ebay also shows an adapter included with that pump.
