1994 k3500 chevy brake booster leak?

Question

i have a 94 chevy k3500 Dually, 6.5l turbo diesel, with hydra-boost brakes, lately the booster has been leaking at the joint between the 2 parts of the booster, not the master cylinder and booster, the 2 sections of the booster, is there a seal, gasket or O-ring that can fix this problem or am i in for bad brakes or a broke checkbook?

Update:

where can i get a rebuild/repair kit for it, tried napa, carquest, kragen...

this isn't as bad as your thinking, but as for rebuilding yours, don't try it.
this is an easy fix, you just need to take the 2 bolts off the master cylinder and pull it away from the booster if you can, but you may need to take the 2 brake lines off as well but in most cases you do not have to, and take the vacuum hose off coming from the manifold and then there's a clip on the brake pedal and 4 nuts on the fire wall under the dash, then just pull out slow and its yours.
the booster should cost you about $140.oo for a new one and $100.oo for a rebuilt one.
i just did one about 3 months ago on the same truck, will a 95 but the same all in all.
if you have to pull the master cylinder you'll have to bleed the brakes, and always start with the wheel closer to the master cylinder first and work your way away from it from there

you can get a repair  kit for the booster that could help you out but you need to know if there is any wear inside the booster body (score marks)before you install the kit  if there is you are just waisting your money

rust holes? vacuum leak? poor installation? many possibilities. you cant repair a vacuum brake booster though. at least not easilly. just replace it.
