Brandon and Dennis...The early cars( up to vin 3466) had a much different accumulator that the latter cars did. I ran into problems when I was changing over to a R134 system as a provider sent the wrong accumulator. Roy 0893 In a message dated 10/23/2005 7:06:12 P.M.

It shows the A/C hose from the accum. to the compressor using a spreader valve prior to VIN 34XX. I think this is commonly refered to as an expansion valve which the later cars don't have. This may be the reason you can't find the high pressure switch.
