Napa AR272 Rated at 30 amps.
I also think a Ford fuel pump or EEC relay will do the thrick. You could try a chevy fuel pump relay or an old dodge ASD relay. I never tried mine on 4 cells because I use my 16 X 5. 10 bulbs is not enough for 20 amps on 4 cells.
JimmyD,
I have heard of guys putting cardboard (business card) under one side to adjust camber. They also make CASTER shimms.
I just put a straight edge over the top of my front tires. If the camber is off, you will see it right away by the way the tire wears.
