No experience with the BPE brackets shown.
Search for the long post on AC compressor options for a slant six. I show a bracket I fabbed, using the roll-your-own Sanden brackets which Charrlie_S linked. You will need to weld. I cut them on my milling machine. I mounted it where the p.s. pump normally sits (have manual steering) as Charrlie_S suggested. I bought the special AC pulley from a member here which fits (barely) between the crankshafter damper-pulley and timing cover. I also have factory Sanden brackets from a ~1978 Volare slant I ran across in the junkyard. It also mounts a Saginaw p.s. pump (if needed). Problem is only 1" clearance to the battery even after I whacked off a sharp corner, so risks punching a hole if the engine shakes too much. That is because Early-A's have a narrower engine bay, as mentioned. But, I'm hoping for future batteries which are narrower. There are already half-sized batteries in some cars (esp. hybrids).
Don't ask me to sell you the Sanden brackets. First, I might use them someday, like if my homemade bracket cracks or I switch to power steering. More importantly, it recalls a bad ebay experience. At the junkyard, I was walking by a 1978 Chevy truck and noticed a Sanden compressor on its straight-six engine. I thought "can't scrap that", so took it and cleaned up, thinking somebody would appreciate my effort. Spent much time researching those engines and what it might fit. Some have the alternator on that side so no-go. I saw it had sold, then some guy from Dothan, AL e-mails asking for photos. I said the listing had ~10 photos and a detailed description, but it had already sold. He said "I bought it" (now he asks for photos!). I asked about his vehicle and engine, but no response. Later, he leaves bad feedback, just saying "doesn't fit". The idiot never even told me what vehicle and engine he has. I saw he similarly left bad feedback to others w/ similar responses of "you never even asked". Thanks for letting me vent. After seeing you fuss at slantsixdan for what he sold you, you are on my "bad customer" list. At least you apologized. I'm guessing still a kid who needs to mature. My boys were rude when they were 13 and played video games.
