Hello

Maybe I am not very helpful, but your question sounds like: "Does somebody have four wheels, and 6-cyl-engine and a stearing wheel I need to repair my car."
Do you really think it makes sense.

> Part 1 Description: IC31 (40H174, latch)
Any electronics supplier (mouser e.a.) has them. Search for CD40174

> Part 2 Description: IC5 (HD6303XO, timing circuit)
Assumingly this is not an "...XO" but an "...XF", the datasheet does not mention an XO and the case dimension looks like it is an XF
