Yes my 87 xtra cab long bed was a 2wd. I also have never seen one in 4x4. I do have an 86 turbo space cab 4x4 with a reg bed though.
I was at a friends house in the late 90s and a friend of his rolled up in a 94 extra cab long bed 4x4. After drooling over it they said he'd bought it from another friend who builds limosines. It was super clean and pretty cool.
