I don't have the Optima part number handy. The Optima came with a different hold down clip for the base of the battery. I wasn't able to use the webbed nylon strap do to it being too lose some mod will be needed.

Due to the terminal locations being slightly different on the Optima I wasn't able to put the plastic cover on. Some trimming of the holes will be needed.

I was a bit confused over Red and Yellow too, but I have had 2 Red Tops before and had no problems. The yellow (deep cycle) may be better for winching.
