I have been wondering about this for a while, but I didnt know for sure. I have noticed that the car seems to be a little sluggish when it starts. I think that it has the origional battery in it, so im looking to replace it. I have heard that if you dont use a certian kind, it will affect the electronics. Im either going with one of two brands, east penn mfg (DEKA) or the interstate. I know that both are reliable, what should the specs be on it? Anyone had any issues just using the standard 34/78 series? Im also looking at struts, and I need to fix the HUD. The spring is broken. I think that its also going to need motor mounts (dogbones), they look to be letting the engine move. I was also wondering about the mounts on the bottom, and did find some on that too.
