I also just ordred an Optima red top 75/35 from AJUSA for $95 and free shipping. Locally I picked up one and the guy said it would fit 78/34 and I told him I needed a 75/35 but he insisted it would fit. NOT
The 75/35 is .200 smaller on the hieght. There has been several posts here on this and the guys that say 75/35 are right.
By the way Chuck the delivery on my battery is supposed to be 4/29 or 4/30. If it isn't in by Friday morning I'll be running to Sears for a temporary battery for your party, just can't miss that now can I.
