front differential vacuum issues

[Empassar]

Hi , I'm a total new guy to forums and such. I'm sure someone has encountered this issue
I have a '88 wrangler 4.2. I got it not running and a total wiring and vacuum tube mess. trying to eliminate most if possible.
Are there any alterations for the vacuum controlled 4x4?
Don't need auto hubs.
thanks for any help.

Yes, you can take out almost all the vacuum system and run just the distributor, brake booster, and the 4x4 system.

I had an 87 and got rid of it all too.
