the gm garage gave me a name of a business from oregon that specializes in 4wd resto parts. but they gave me no pn# or address. it is called "holerook 4wd specialties center". anyone heard of it before. im hoping they can find me my 4wd selector pointer that fastens to the 4x4 shift stick under neath the knob by a collar and a set screw. it runs down the boot and over the gear position plate. some models had these and some didnt. i dont know why. was it an option ? they ran fron 69'-till 79' on three different t-cases. pictures of this item can be seen in chilton's blazer/jimmy 1969-82 manual on pages 186 &187. thanks ahead of time for any and all info.
