Here is a bypass that I made up to use when I was working on my servo projects. the scale is hard to see in the photo but indicates a length of 3.8" center to center on the fittings. This is all 1/8 NPT stuff except for the brass fittings which should fit your existing female flare fittings, yours may be different. I put the 'T' in to make bleeding easier, but after using it I think two ells would have worked OK. Be sure to secure this to the old booster bracket as it will subject the lines to vibration if you don't.

OK
PS Be careful when removing the old servo it is full of brake fluid!
PPS I would NOT refill the fluid and drive a car that has just done what your's has in traffic! Just MHO.
