I can't swear this is correct, but I found a manual for a 1980 GT18, 917.257120. It shows a single cyl. Craftsman engine. Drive belt is a 6474H. On the 1980 44" & 50" decks the mower drive belt is a 3704J. Sizes below;

6474H = 21/32" X 81"

3704J = 21/32" X 100"

 

I'll get the manuals also.

 

We have the deck manual!

The engine to mower belt should be a 5/8 x103, I use a Napa B100 or BL100, can't remember, it's there fractional belt designed for friction drive.

The 42 and 48 use the same drive belt, just different under the cover deck belts.
