IMO, about he only way to go about it would be to find a complete donor or a take-off setup say on EvilBay.
Have the booster rebuilt along with the MC. If you are dead serious on numbers correct, the install has to come from an original (unmolested) 1955 as the booster itself has an updated 1956 PN and I would assume you want 1955 ID NOS.
I will look around for you in the meantime.
