yes ask for the floating amp regulator it will float to 90 any bump or spark will snap an older black regulator so don't ever jump any 1 or if you do carry a new box with you the silver box floats to 90 wich has 1 drawback and its frying old wiring if you have any cracked wires retape or replace or chance of a fire jumps 80%. I burned down 1 65 barracuda because I updated the alternator and the wires caught a fire before I ever new y the old wiring is 1/2 the size it needs to be and 50 years old and cracked leaving it exposed to ark . Ark and old oily and fuel dripping engine bays can really burn your azz because a $9 part or a 2 cent splice. leave the fire for the nitro bouyz good luck have a fun and safe summer
