I am about to have some stamps made for the various markings on my 8.75 housing ('70 Swinger, 340 3.23 SG), and two in the pic below have me confused. They are located between the center section and the spring perch. Does anyone know what they are? It looks like TSA (or maybe T8A), and below that 193T.

Thanks.
