For some reason Vans doesn't seem to use 3/32" pulled rivets anywhere (at least that I'm familiar with). There are a few places where using a couple of these would really help. Is anybody aware of a P/N & source for these? I'd rather not upsize to a 1/8" pulled rivet.

Here is one source I came across:

I'm actually a little baffled about pulled rivet materials - are steel mandrel / aluminum rivets preferred? Corrosion? Aluminum mandrels? This is for a low-temp application, i.e. holding skins in place.
 
Where 3/32" pulled rivets are needed, Van's generally recommends the MK-319BS. These are actually 7/64".

They're also made of monel, an alloy of nickel and copper. We use lots of them in the HP-series sailplanes. I have a bunch in stock if you can't get them elsewhere.

One near-equivalent is the MSC-32 Cherry commercial rivet; it's also Monel but it uses a true #41 hole instead of 7/64". However, Aircraft Spruce has dropped them from their line, suggesting builders use the CCC-32 stainless steel pop rivets instead:

It looks like Wicks still has the MSC-32:

As well as the MK319BS (at $0.36 each):

I'll gladly let them go at 15% less than that.

Thanks, Bob K.

MK-319 BS

Van recommends MK-319 BS for 3/32 (AN426-3) replacement in the wing walk area if you can't get your hand in the close fit ribs to buck the AN426 rivets. The MK-319 BS has the same head diameter and is a flush rivet.
You do have to drill the hole bigger, #35 or so. Vans says to drill 7/64ths.
I just stuck the rivet in the drill gauge, and picked the smallest hole the rivet would easily fit. I used that drill to increase the #40 drilled hole, then installed the MK-319BS.
Cherry makes a 3/32 pull rivet that is accepted for holding platenuts, but platenuts are held in place by the fastener when under load, so the rivet isn't really used as a structural part in this application. Also, Cherries are more expensive than Van's offerings. Still, driven rivets are so much cheaper, stronger, and have a better finish that it's well worth our time to learn how to use them as much as possible.
Opps! I posted this too slowly and several guys beat me!!

Nutplate rivets

As mentioned, there are also the nutplate pop rivets available from Vans (only in the short length) and Bon Aero:
