Freeze cups D3VE-A2A heads?

I own a '72 continental Mk IV, which has D3VE-A2A cylinder heads. These heads have freeze cups at the front and at the rear, blocking off exhaust passages, probably for some kind of environmental purpose. These freeze plugs are starting to corrode and leak exhaust gas. Does anyone know what size these plugs are and where to get them? I live in Europe and these parts are not easy to find here...
I tried to post a picture along with this thread but that doesn't seem to work!

linkmkIV,

I am out of town at the moment and need to double check the dimension,...but I think the plug is a 41/64" and available from Clevite. I will get back to you in about 48 hours when I return from my travels. Also, you may send me an email via our website (in my signature line below), and I may be able to send several of these plugs to you for a small fee.

Re: Freeze cups D3VE-A2A heads?

As I measured it, it came to about 16.7 mm, which is (I think) 21/32 or 0.656 inch. I have been able to plug the hole with a 16.4 mm freezecup and some 'exhaust-paste', but since there are four of these cups and they are all the same age, it may be wise to replace all of them.
I'm anxiously awaiting your reply.

You're very close in your 41/64" estimation; the plug we use is a 43/64" and is available from Clevite (through most american auto parts stores).

I can't be certain that your 16.4 mm plug wont work, but I advise against the 16.4 mm plug you installed because I feel it may not be a long term repair due to its undersize. Just an assumption...
