How did you do that adaptation?

I then milled out the SL66 mount so that the Hasselblad prism would sit down inside. I milled it as deep as I could without compromising the integrity of the metal but thin enough so that the screws would go through and engage in the Hasselblad prism.

Actually, I countersank the screws to make it look nice.
The distance of the Hasselblad prism from the SL66 ground glass doesn't matter because the Hasselblad metered prisms have a focusing diopter. I can send pictures if you are interested. Also, you could send me a Rollei prism and a Hasselblad prism and for $75, I'll do all of the work and return a finished metering Rollei prism.
What started me doing this is that my Rollei prism was totally de-silvered and impossible to use. I picked up my Hasselblad prism and it looked like it would fit into the Rollei prism mount. So I took the Rollei prism apart and discovered that it could all be done with just a couple of hours of work. I first mounted my 90 deg. Hasselblad metered prism. I then asked around and found another bad (de-silvered) prism for $50, so I bought it and used it to mount my 45 deg Hasselblad metered prism.
My Hasselblad is a 205FCC which is all electronic, built-in meter and all of that, so my Hasselblad 45PME and 90PME were just sitting around. I have non-metered prisms for use on the 205. I was actually contemplating putting them on eBay until I got the idea of putting them on my Rollei SL66.
