In need of help

[69GWC]

I just bought this 69 4x4 acouple weeks ago and have a few questions on it ,
first the TC i dont know which one it is and its not sending any power to the front drive shaft and was wondering who might know the model and maybe why its not powering the front.
it does have lockouts with a D44 .

2nd, who makes disc brakes for the front so i can get the drums off.?


3rd, 33,12.50s on 10" rims do you think they will fit with know lift or maybe just longer shakels on the front.? or should i stick with 8" rims.

thanks for any help you can give me .
