Good morning everyone. I`m currently working on an 11B built 68 RS with the L30 327 and Powerglide. The car has factory AC which is what I`m attempting to put back together now. Late last summer the compressor (not the original) failed, and I`ve now gotten around to sourcing a correct replacement which has been professionally rebuilt. I also had the POA, expansion valve and receiver dehydrator assembly serviced by Classic Auto Air as I`m converting to R134. Hoses have therefore also been replaced and the evaporator and condenser removed and chemically cleaned.
Last evening I was working on some of the final reassembly when I noticed something odd with my AC muffler. According to the AIM, its not the right one! Sheet D3 (pg 213) indicates a different muffler for a V8 (PN 3923194) than an L6 (PN 3925797). It would seem I have an L6 muffler. As indicated above, the compressor had been changed, so the muffler could have been changed at the same time, but I don`t believe that to be the case. I have also spent a few hours looking at any photos I can find showing that area of the car and have noted a lot of V8 cars with what would appear to be the L6 muffler. Obviously I want to be sure I`ve got this right before I run hoses and have the AC system charged.
If anyone can confirm whether or not the L6 muffler was used on V8 compressors, it would be most appreciated!
Of lesser concern is a clamp that I have seen in some photos that holds the muffler to the compressor. That said, I don`t see this in the AIM and it would seem to me to be unnecessary as the muffler appears to mount securely enough on its own.
Was this clamp used with this style of muffler
