What transfer case do I have?

I have a 63 chevy k10 pickup with an sm420 tranny. I don't have any pics right now, but can anybody tell me what transfer case I have or several ones that I could have? Thanks!

I would guess it might be a Rockwell T221. I know 1969 was the last year they used them in GM trucks.
Pics would help.

If its married to the transmission I would guess the rockwell. Hard to guess what could have been swapped in there over the years though. There were some divorced cases back then like the dana 20 and 205.

No married cases in '63. The 205 didn't come out until '68, and I am pretty sure that the Dana 20 was not available that early either. It is either a T221 or an older Spicer box like the Napco trucks used.
