Freeze Plug Question!

I am doing a freeze plug swap on my stepdad's 85 GT, and Was trying to remember if there was a Chevy freeze plug I could get that has a thicker contact area for the bore in the block. These ford ones are thin! I remember reading either an article or a post here (maybe on some other board ) where someone had told me that a certain chevy piece is the same diameter, but has a wider lip that helps to get on straighter and such. Any info on this clarification would help me out alot. Thanks fellas, hope all of you have had a great new year so far!

I've got no advance auto parts within 100 miles of me. Could someone help me out with a part number? Thanks
