no h/o alt yet cuz toyota is too $$$$$ but i did find out that theres a conversion alt kit you can do its a 2000 s-10 alt that almost bolts right up and to get the s-10 alt rewound to 220 its only like 180 bucks around here but im running 2 optima yellow tops and i re grounded my alt to batt batt ground and chassie ground and that took away the dimming

2 sheets for an enclosure that's about 4.7cubes is a bit excessive, trying to be save money at the while be efficient. im gonna go with a width of 49"; that way i dont have to worry about the measurements being off. but going for a width of 53 is good because it kinda fills in the gaps.
