My bro just went electric on his 69 C10. He loves it, better gas mileage+ much better cooling, & his had all shrouds,fan etc all good shape. Got to have a good alternator tho. I am in the same boat as you(no shroud,reg fan), my 64 cools OK now but when I get the A/C going I know it won't. Thinking about an electric. I can only imagine the hassles you encountered getting it charged. Brian
