Yarn substitution

[Upnorthchris]

I have an old pattern calling for Unger Cozy Yarn in 1 3/4 oz balls. Anyone know what is a good substitution. The project is a hooded coat. Thanks for help.

Does the pattern give you the gauge--the number of stitches per 4 inches or 2 inches (or even for 1 inch)? That will help us figure out the yarn weight.
