There should be a tag on the back of the t-case with the ident #.
The 208 is an aluminum case and uses a rear slip yoke.
I believe you could find some 5 speeds in these trucks in 87 and up.(could be wrong),but they were also a weak tranny.

If it is just going to be a show truck and for cost reasons i would just find a
4 speed manual with what ever t-case you want to run and swap that in.

When i did my swap i went with the cast iron gear driven NP205 t-case,just for durability issues,as it gets used hard.
