need the year to be exact, but most series short beds had a 112-115" wheel base, the 3/4T long box and 1T extra-long box had about a 122-135" WB - you might even have a 1.5T, which they didn't make a bed for .... the number on the vin tag should tell what model you have, although if it's a '38 as your handle suggests that may be long gone .... lots of factory info here, including the GM resto-packs
