Hmmm, well no pictures exist as all this pre-dated digital imaging but I had a York compressor mount for a 235 I bought around 1975 or 76. It wasn't a dealer installed option however. Aftermarket affair made for and sold all over the USA by Four Seasons in Ft Worth. There were as I recall 3 York models people used...206, 207, 208 depending entirely on the cfm output. I had a 208 with an aftermarket MG unit I installed under the dash. The mounting affair was stationary...a heavy 1/4" thick bracket that attached to one head bolt, a water pump bolt, a special bolt you had to install on the intake/exhaust manifold and a couple of other bolts. There was always an idler pulley and you had to install or have already an extra pulley for the balancer or a 2 belt balancer (not too common). The York compressor sat on a metal shelf and was attached by 4 screws.
Note: I mounted the unit so it blew through where the speaker vents were. Not a terrific idea and I changed it asap. Made the dash condense water like crazy and very soon you'd have a wet floor.
For what it is worth I am not a fan of York compressors for many reasons (and in the 60s and 70s I owned about half a dozen). And that is putting it as nicely as I can. The Sanden type are greatly improved in all aspects. I don't believe you can get a better one than the Sanden SD-7...especially for the money and the mounting scheme for the 235 is much more well-designed.
In the 1980s Four Seasons made an odd-looking adapter that would let you adapt a rotary compressor to one of the York mounting devices. A friend did that but I can't recall how it worked.
