Maybe a rockwell t221. Not sure about the serial #. My 67 3/4 ton came with the t221, but had a 327 instead of the 350. what tranny does it have?

I'm not sure what the tranny numbers are but it is a 4 speed standard.

What does the shifter nob say?? If it goes L 1 2 3 R then I believe it's a SM420 but if it says 1 2 3 4 R then it's a SM465 which isn't the original tranny. The motor may have been the only thing swapped so you might still have the original tranny and xfer case which should be the 420/T221 combo.

Re: Transfer Case Number...c-98404 A10?

what is the shift pattern on the t case. My t221 is 2wd all the way forward, then 4hi, N then 4 low. Np 205 is 4low all the way forward, then N, then 2wd then 4hi pulled back towards seat. Don't know if this helps. I will try to find a spot to look up the tcase number.
