Reaudio.com has a nice box building calculator to figure out slot ported length. But I noticed you are trying to fit it in a s10 so round port might be a better choice. I'm going through the same problem as you but with a regular cab ranger and I've been using this link to see what I can fit in there.

For a 2cu ft box tuned to 34Hz:

Slot port

30 sq inches port area (10x3" slot for ex.)

28-15/16" long (29")

Round aero port

6" diameter port

28-9/16" long (29")
