if anyone has part numbers for optima blue or yellow tops that will fit that would be great. Thanks

 

Get the 75R/35. The fit is perfect and you get an extra set of posts on the side.

 

I don't want to go with a red top because I have 4000watts of stereo equipment and bags on the way so the red top won't cut it I don't think

 

Ah, nods. You need the yellow or blue... You might need to get an extender. You need to have the posts offset to one side.

 

What about the D75/25 Yellow. It's the same group designation as the 75R/25 with the correct dimensions and the posts are offset not needing an extension bracket. The bluetops do not have a group 25 so you would need to go with a group 34R base with a 1" adapter. I don't know where to get those, I just know they are made. One other option would be to have a secondary battery (bluetop recommended) specifically for the stereo and bags.
