Well I need to replace my brake booster on the '75 Wagoneer. I have heard of running a dual diaphragm booster off of a j20 I believe.
It is a bolt on deal correct?
How does the pedal feel? I do not want overly boosted brakes or touchy brakes by any means. I do tow with the Wagoneer so brake force is important but honestly with my dead booster the brakes are still pretty good. Haha.
Should I go with a dual or stick with a stock single booster?
Thanks
Jay

Go with the dual. I did with my Cherokee when the booster went out. Pedal is fine. It was bolt in. A bit longer than single but you can move the MC carefully. No draining or bleeding of the brakes required.
To keep your current master cylinder use the 75 J20 booster.
To upgrade to the more modern MC use the 87 Gwag booster.
Don't buy a "Loaded" booster. If the MC or the Booster fails you'll have to warranty both at the same time. Swapping a MC and booster intead of just a MC in a parking lot on a road trip sucks.
I have the j20 one in my wagoneer. Works well from what I can tell. I was weirded out initially because coming from drum/drum where the pedal only moved like an inch and required both feet to do that. The j20 booster allows me to damn near press the pedal to the floor with 1 foot with ease. There's significantly more movement involved, however, to achieve the same braking result, than with my drum/drum setup.
For you, it'd be direct bolt in, for me, i had to change a whole ton of stuff.
Well it ain't just the smoke and the traffic jam that makes me the bitter fool I am But this four-wheel buggy is A-dollaring me to death.
