I have to replace these rims, right?
It looks like the eyelets are slightly coming out of the Matrix Anodic rims on my 1984 Trek 610. These are the worst eyelets front/rear respectively. The front has more separated eyelets than the rear. (sorry about the cat hair 
)
Front:
Rear:
Assuming these can't be used, does anyone know a way to measure ERD without taking apart the wheel first? I'd love to get period correct rims but I imagine I'll go with Sun CR18s due to cost.

i have to say i can't see any eyelet problems in the pics. but there's nothing wrong with wanting a set of new wheels, especially if they are to replace some very old and beatup ones. i've got a couple of wheel sets with sun rims. they've given me no problems.
and there are more than a few here that can help with the ERD question. i'm sure they'll be around shortly.

If the rim itself isn't cracking, there's no real concern. If the gap between the eyelet and the rim bothers you, you could use a hammer and punch to seat it more closely.

It's not rare at all for the eyelets to pull out slightly double ferrule on Mavic rims. I consider it part of the settling precess, and suspect that it's because the eyelet wasn't clinched tightly when the rim was made.
Possibly the larger part of the system - the inner ferrule - wasn't fully seated when the rivet was clinched. Then when the rim is built spoke tension pulls it all inward producing the effect you have in the photo.
Next time you have the tire off look inside the eyelets, and you'll see that there's something close to zero chance of these pulling through until/unless the rim cracks at the spoke holes.
My advice --- stop looking so closely for flaws o problems and ride your bike.

Agreed with the above. Monitor the spoke tension eveness and rim trueness and deal with things when these get off. Andy.

1984 Wheels? Those wheels are 30 years old. My last pair of Mavic Open Pros made it to 33,000 miles over 8 years and I had to replace them. I did have a bad race in the front hub though and the rear rim was bent.

Oh good. I was hoping it wasn't a big deal but I was sure I'd be told they were shot. 
Since I could see gaps between the rim and eyelets I thought perhaps they were pulling through from the tension. I will check the inner ferrules and see how they look.
They've stayed pretty true for quite some time so that's probably a good sign.
I really appreciate the help. Thank you!

Double ferrule rims do that . the spoke tension squeezes the double walls and the outside spreads a Little

Do look for cracks on older Matrix rims though. I've found a few over the years.
