Yep, that they do, but no real remedy. I have an Optima in my 35 PU. I built a metal box the size of a Ford battery and turned the battery at an angle from corner to corner, with a strap going from original post to original post and then used the original hold downs. Works like a charm. I used the original floorboard pattern but then cut the floorboard where I can remove just enough of it to get the battery out. If I could overcome my blockage to posting pictures, I would post pictures. Really neat modification.
