I found this NOS Blaupunkt installation kit a while back:
It includes a speaker, mounting hardware, knobs, escutcheon, trim plate and complete installation instructions — everything you need except the antenna and the radio itself. The trim plate in particular is a sought-after part in the Type 34 community. Brand new ones almost never come up for sale. The speaker has never been unwrapped. It's been that way for 40 years so it can wait a little longer until the Ghia's finished.
Here are the installation instructions in case they're of use to anyone (click to enlarge):

Noise suppression instructions for FM radios:
I have a very clean used Blaupunkt Frankfurt AM/FM/SW radio that I'll install in the Ghia using this kit. Since it's a universal kit for fitting any Blaupunkt model to a Type 34 Ghia it doesn't include any parts that are specific to certain models. Those parts were included with the radio. Unfortunately that includes the chrome outer knobs seen in a Type 1 Ghia in the photo below, which I'll need for my Frankfurt:
If anyone knows where I can find these knobs please let me know!
