HELP!!  I know somebody makes a cable system for a 1998 Dodge Ram 1/2 ton to engage the front axle, but who makes it??  I don't want to use the vacuum motor.  Thanks for any help you can offer!!  

Don't know offhand, but I know JC Whitney sells a cable op override, but I can't remember if its just for Chevys or if its for everyone. Do a search on their website.  

Here's what you are looking for:
