821.6 freeze plugs, who has them?

[dieselherb1]

I read somewhere the freeze plugs are 36.5mm. I checked Advance auto they only had 35mm or 1 3/8(same size) does any of the parts house(brick and mordar) have them?

"dorman brand 555-103
My suppliers computer shows them as 36.5mm but it also said their actual size was 36.7"

Just passing that on, from coolair.
NAPA has them.
I've heard of Meyle sometimes being too small, fits too loose.
 I got some of these and they felt tight.
