1989 ford thunderbird std brake system vacuum booster install?

My 1989 ford thunderbird standard brake system needs a replacement brake vacuum booster, because the original one was broken. The rod and spring which attached to the brake pedal linkage came out of the boot. Because this rod came out of the diaphram hole of the brake vacuum booster, removal of the rest of the booster, the disk, was not that difficult. Unfortunately, I cannot get the replacement brake vacuum booster installed because there is not enough room to squeeze the booster with the rod attached into the area where the rod goes through the firewall hole to be bolted down. The Hayes manual and the instructions that came with the part both say to just slide it in and bolt it up, but the part appears to be a little too big to fit between the the firewall, the engine, and the wheel well. Do I need to pull the engine or something? Is the 1898 brake vacuum booster rod removable? Should I force it down into the area, risking bending the diaphram?

    The part is the correct one. How do I know if the rod comes out. I do not want to damage the part.

There are a Couple of Different Variations on the Boosters. Make sure that you have the Correct one First. If you do, Just work it, Some of the Rods are Removeable by the Way.

When i push down on the brake pedal air leaks out around the rod and the pedal goes to the floor.

Check the vacuum line on the power brake booster, the diaphram may be pushing the air down the rod, the break booster may be defective all together if the vacuum line is intact.

I have 1996 ford thunderbird lx 4.6 liter v8 engine and how do i remove power booster brake from the firewall!

Pull the vacuum hose off the booster. Disconnect the brake lines from the master cylinder. Remove the master cylinder. Remove the windshield wiper motor if it's in the way. Inside the car, disconnect the stoplight switch connector. Slide the stop lamp switch off the brake pedal just far enough for the outer arm to clear the pin. If you have cruise control, remove the speed amplifier. Remove the booster attaching bolts/nuts. Slide the booster pushrod, bushing and the nylon washer off the brake pedal pin. In the engine compartment, pull the booster forward and rotate it until it is free. Good luck!

Replacing my brake booster

go to the master cylinder and remove it from the booster, disconnect the vacuum line from the booster, then disconnect the brake plunger from your brake pedal inside the vehicle, then remove the booster mounting bolts from inside the vehicle then remove the booster, install in reverse order, once you install the master cylinder, you will need to bleed out any air in the brake system, hope this helps, let me know
