Wow really?! I didn't see one...people say its real expensive so that is why it is usually not included, I found a used one for 50 bucks from a salvage yard, hopefully it will be there after work today.

All the other years seem to come with a reservoir, is there anyway I can use the 99 wj booster with another year master cylinder??

Adjust your rear shoes up.

WJ versus 95 to 96 XJ booster

Actually, the WJ booster is in some ways easier than the 95 to 96 XJ.

I've done both.

XJ, you don't have to mess with the firewall. No big deal anyway.
But, you have to move the washer reservoir. And, once the original booster comes out, the bracket inside the cab moves and makes it a bear to install the new booster.

WJ you have to bend or cut the firewall lip, but don't move the washer bottle.
As an added bonus, the mounting studs of the WJ booster are a bit smaller and it's easier to get in.
Another bonus with the WJ is that it has FLEXIBLE lines from the master cylinder that make putting things together MUCH easier.

And, WJ boosters are newer and easier to find…..
