M1114 Brake Booster Leaking

[Mohawk]

Hi All...still working on getting my m1114 roadworthy and running...seems after filling my power steering res, I have a leak on the inside of the firewall at the brake booster rod...question...is there a seal kit to fix this or do I have to replace the whole unit?

There is a seal kit, I would have to see if I have the number, it is a "universal" kit that has a couple different size seals.
You will need a seal lip tool like pictured and do not follow the youtube videos where they just cram the thing together and hope for the best as you will likely ruin the seal.
I am super busy right now but will TRY to put together something in the way of instructions.
Others should also have experience with this.

If I was to replace it with a whole new unit...my research shows a Bosch cross reference number 0204022603 as the correct unit...can anyone confirm this?
