Paul, I believe what you have are REMAN assemblies for a LYB HT 302-332 engine(s).
The third PN PREFIX CHARACTER Q (B8QH) indicates HEAVY TRUCK, in this instance LYB.
The third PN PREFIX CHARACTER T (B8TZ) indicates a FYB HEAVY TRUCK (292MD - HD).
I think I have the ratio(s) on another computer which is in ICU.
