electrode vs pilot assembly vs entire retrofit

I've been trying to locate a white rogers pilot spark electrode> The electrode goes in a pilot assembly E50-104. the porcelain is cracked and spark is not going where it should consistently..The retrofit kit from weil mcclain is over $400 the pilot assembly can be found online from air dynamics for $148 ups ground delivered... Can I find the electrode? A white rodgers 760-56 does not line up properly.

Is this on a

White Rodgers Cycle pilot system? If so the what is the number of the gas valve? The 760-56 is the spark for that system unless you have a 36E gas valve then it is a 760-310.
