Did the 40 amp switch this weekend and thanks to johns toolkit and bills (silver streak) help is wasnt too bad we had a few glitches mainly figuring out how to remove the old alt and installing the new but once we watched the video on u tube on how to do the 60 degree install it almost fell in i told bill it was so easy he should take it out and put it back in hahahahahaha one thing we had a lot of trouble with was trying to pull the lewis pin out no matter how hard we pulled it would come out so i thought i would have to pull the pan and get it out luckly my oil sight glass was leaking so i wanted to change the o ring on that well when i took that off i saw i could just take a long screwdriver and knock it out came out real easy so i think better that pulling the pin with the wire its much easier to remove the sight glass pop it out and use the wire to remove it all in all an easy weekend job i know i could do it my self thanks again Bill and John
