SS heat exchangers

[crodog2813]

Help:
I am new to this form so here goes. I looked under my 88 Targa and it loook to me that my heat exchangers are in very good condition. They appear to be stainless steel. How can I tell if they are the SSI's or original equipment. there is a number and an insignia on them.

thanks
