Are the current thin-flange SSI's available without the MFI heater tube?
Backdating a '75 car and I bought these on eBay:

But the heat exchangers I received have the MFI heater tube on the driver side:
Both the eBay listing and the box show a part # of 91.911SSI.
I've had older SSI's on a couple cars that did not have the heater tube but wondering if that version is no longer being made under new SSI ownership. Any ideas?
