LD4B how good and how rare what are they worth?

Read what I wrote. I said it's an LD340 FOR THE 318. In other words, it's real close to the LD340 but FOR THE 318. It has 318 sized ports, so it's FOR THE 318. It's designed SIMILAR TO the LD340, but made FOR THE 318. Which is what I said. Thank you drive through. ;)
You are absolutely correct! And I'm an idiot! ;)
