Sanden Compressor and Mounting Bracket
The wing cell bracket (dimensions shown below) is part # 64-52-1-284-953 might be found on eBay or try Al Taylor - [email protected] @rsporsche
Might have to grind some of the wing cell bracket to allow it to lay flat against the block as it might interfere with the rib on the block. @Dan Wood
Others have had to shim the compressor bracket to the wing cell bracket. @Luis A.
L.C. Wylie & Co. Sanden Compressor Bracket https://lcwylieco.bigcartel.com/
1974 only - 74 is the only year with this unique bracket and compressor, part # 64 52 1 272 240. The original compressor has a mounting ear on the very top and vert bottom. @HB Chris
Compressors
-switch from old York boat anchor to "Sanden style" 709 compressor and York mounting bracket from Johnjoysyl eBay seller ($190 for both and must be at least a 15lb weight savings): @Stevehose (Steve has later recommended the L.C. Wylie & Co bracket per above)
508 or 709 works just fine. There's a lot of variations of both, different fittings and different sized pulleys etc. This is the one I like. A 709 with a 125mm pulley. Larger pulleys work (132mm I think), but can make installing the bolts more difficult. The 508 has 5 pistons and the 709 has 7. There's very little functional difference, I've used both with great results. But in theory the 709 is the "better" one, so I usually go with it if the price is about the same. @Layne
We buy from authorized Sanden dealer. I don't buy knockoffs because I have to replace them for free when they fall apart.

Compressor Belt
***************Looks like the best belt choice is either 9330 or 9335 (see below)************** However, several lengths will work.
For AC I used Gates XL9345 (12.5/13mm x 885mm). I have an unknown (not stock- looks kind of like yours) compressor mounted on one of Layne's brackets. @TedS
Optional Belt Numbers same as XL9345 @Dan Wood
12/12/2021 For Sanden 508 with Layne's bracket
And the winner is...9335 (same as the one Chris has on his E12 with the same bracket and compressor as I have). I think the last three digits are the length of the belt in 10ths of an inch....so a 33.5" belt. I think Steve's Napa 25-9330 would probably work also. per @Dick Steinkamp
Non original pulley options will require different belt lengths.

Hello all, I have a very small one-man BMW restoration shop that I call L.C. Wylie & Co. and I also make and sell these brackets to convert your air conditioner to a modern Sanden type compressor. The original compressors are inefficient, expensive, and very hard to find a reliable new or...
