Anyone used one in an '87+? I know they use an 80 amp and I am sure there is a good reason. I was thinking of getting the 70 in a pinch. It is a lifetime warranty..... Maybe it will work for a while.... The 80 amp is 2x$ and parts are also expensive. Any info would be appreciated. I would rebuild mine and put it back on when I get $$$ just need somthin to get me bye untill then Thanks.
