Fluid leak, Booster and Brakes

[DCMille290]

Hi everyone,
I am not sure what's up but I found fluid leaking from between the booster and the master cylinder. I noticed the top of the frame rail wet, directly under the booster so I assume that's where it's from.
Brake pedal seems to bouce or push back when I push it down a little bit while sitting still and the steering feels a little tough.
I haven't ever replaced a hydrobooster if that's the problem, doesn't look too hard. I do have a new PS pump and a new PSC box.
Any suggestions on how to replace the hydroboost and where I can order one from would be appreciate. We are on a road trip from FL to PA.

Thanks in advance.
