I have searched to the end of the internet.
Can anyone point me in the direction of a L59-1.25B-180-30?
Everything I have found so far is either 3" or 7" in length.
Thanks for your help.

Call them for a replacement number

A-1 Components, LLC. (800) 759-2872 (http://www.a-1components.com/)

Thanks - I spoke to them, but no luck in finding this particular part. Looks like it is just too old.

I am sure something can be substituted. You will need to look around some more.

No luck yet.

You might not find it and have to substitute something else.

Can you take a picture of this part ( out of furnace and on a piece of white paper so we can see it. I think then we could tell you a part that would work.
