Does anyone know the difference? I tried a search but didn't find what I was looking for.

Jeg's lists the 1470 for LT1/4

Good question. You should probably give them a call. Most use the 1406s, D ports. Notice the dimensions for the ports are quite different. I'm curious why they would specifically state that the 1407s are for lt1 annd lt4s.

Let us know what you find out.
