Optima Yellow Top D31A
Hello to all,
I just bought two brand new Opitma Yellow top, Model D31A. I remember from reading previous forums that they are a tight fit. I bought the batteries and got them into the trays. Now I am having trouble bolting them down. I thought I read somewhere that someone fabed something up. Who was that person(s) and what did you do? The current bolts are not long enough since the D31's are taller. I went to the local Home Depot and Auto parts store, but no luck. I tried searching on the forum and didn't find anything. Thank you to all for you help!!

The passenger side slid in perfectly. The stock battery bolts are a bit too short. You could get some allthread stock to replace it. I work in a manufacturing facility and I had some friends out on the floor to weld in a piece of material. I then shot them with some spraypaint and I'm good to go.
After a LOT of research on this topic I am convinced that the group 34 Optima Red-tops (probably the most widely available model?) will do an excellent job in these trucks. If I ever trade up to a 3rd gen that is what I will almost certainly get................
