Proportioning valve part number for an 88 turbo coupe

I'm trying to verify the part number of a proportioning valve I got out of a junk yard. It's 148-8 E7SC-2B091-BB and supposed to be for either a 87 or 88 Turbo Coupe

The E7 in the part number = 1987

Thanks turbobike. I have an 88 LX in which I put a complete braking system from 88 Turbocoupe due to the insufficient braking of the LX. I'm not sure if I can use the same proportioning valve. I took the proportioning valve out of the parts car that was in the junk yard, but I just want to verify this is the correct one. Thanks again for your help. Also is there a site online where I could find parts numbers?
