4.0 Freeze Plug Question

[kess4667]

I have a leaking freeze plug on my non-sohc 4.0 explorer. Of course, it's the one in the back on the passanger side behind the exhaust manifold. I went to a couple of auto part stores today and they didn't have any info in their computers, but one of the shops had a bunch of different rubber plugs. So, my question is does anyone know the correct size of the 4.0 freeze plugs? Any help would be greatly appreciated.

My handy dandy tape measure says they are 1.5" diameter by .25" deep.
