I'll use whatever impeller is asked for,it is just that I had issues with drilling the plastic and it fracturing and in some instances breaking off the brass hub.I modify the pumps the same way,just minus the pinning of the plastic impeller. Ed

Note that the first photo that Roger posted is the Laso pump before the modifications (the pulley looks quite different after the mods).
Since you pointed that out a week or two ago (first time I posted some photos), Barry, I went ahead and followed your recommendation of using Permatex 98H gasket sealant on both sides of the gasket (I'm probably opening up a religious war on sealants and pump side / both sides here, but that's OK).
I'll report back on whether or not any leaks occur.
I appreciate Barry pointing this out (assuming they really are bigger holes; I need to clean the gasket and sealer off my old WP — which appears to be a Porsche unit with a smoother casting — and compare them) and think it would be prudent as these products are released to build a knowledge base of best practices with respect to their installation. In this case, I wasn't seeing much of a downside (other than a little time with some lacquer thinner next time the WP is replaced) of doing a both-sides seal, just to be safe. And I believe the Lasos (if they really do have slightly larger bolt holes) have been installed before, anyway, so there's probably already a track record of whether or not there's a problem there.
IMHO, it's great that Roger is carrying these now, as it eliminates the hassle of having to buy the pump first and then send it off separately for modification. And I greatly appreciate the peace of mind of reducing (or almost eliminating) the likelihood of a WP-seizure that we all know occurs from time to time (see, for example "Close call.........seized WP on the side of the Rd.") and that can lead to major damage.
Anyway, here are a few more photos after installation:

not to hijack the thread but what kind of tensioner is that on your A/C compressor. Also, why is everything so clean?

A few questions. I thought the PKensioner would not fit on early cars with the old style A/C bracket? Not sure which years, but definitely on my '78. It has been over a year since I did that one, so correct me if I'm wrong.
Are you thinking about making a package deal: PKensioner, Gates belt, new style pump??

I walked away from the computer last night after the first couple of posts. Catching up this morning.
Taking Borland's comments in a positive way we need to add some notes to the instructions that recomend the use of gasket sealant on both sides of the gasket.
We supply a new gasket with all our pumps and it is a Porsche supplied one.
No core charge with this new pump.
Tim you are right the PKensioner will not fit the early cars unless you replace the AC bracket.
Package deals are my favorites - so yes I am sure I can.

Because I couldn't stand how filthy it was a little earlier; I just had to stop and clean when I was at this stage:

Ed,
Not to get this thread off-track, but could you please post some pictures of a pinned metal impeller? I am very interested in this procedure/option.
Thanks

I think the name is fine also.
I do have one very pointed question though, is it guaranteed that a metal impeller pump can never get into the block?
That is assuming it is given a normal amount of maintenance.
Obviously a metal impeller will be better than a plastic one as far as durability goes.
