Re: what options were available for '67 4x4 ?
No,the case is the same one. This is how all 4wds were originally made,then someone came up with a way to disengage the wheels from the axle so the drivetrain wasn't being turned by the wheels when in 2HI. When in 2HI you are disengaging the front driveshaft,but unless you have free wheeling hubs the wheels will turn everything back up to the transfer case. Lock out hubs were an after thought to save drivetrain wear & tear,gas,and tire wear...as well as power. In a truck with lock out hubs you can drive in 2HI and keep the hubs in "Lock",which would be just like having what Timbro has. With the hubs locked,or having slugs,you can shift from 2HI to 4HI on the fly whenever 4wd is needed,like on patchy snow.
