Replacement rear evaporator core doesn't match OEM
My 2005 Trailblazer EXT LT (V-6) leaks Freon (refrigerant). Two service stations told me that the rear evaporator core leaks and must be replaced. Now the service station selected for the work is telling me that the replacement part does not match the original equipment. The story is that GM switched suppliers mid-way through the model year. They tell me that they don't know how to make the new part fit my system. They have indicated that there may be additional parts required at substantial additional expense.
Is this legitimate? If so, does someone out there know how to install the replacement part?

Regardless if they switched manufactures the correct part is available. They need to order it using the vin number. If the can not get the right part then they are incompetent.

Replacement Evaporator
The replacement part was ordered with the VIN. GM's direction was an expensive conversion kit that would have at least tripled the parts cost and added 2 hours billable labor. The change would have been a 50% increase over the original estimate.
The service tech ended up drilling and tapping two holes in the replacement evaporator so that the sensor could be mounted to it in the same fashion it had been mounted to the old part. Expensive conversion kit averted and job completed at the original estimate.
