Im going to do the pulley swap. I know i need the crank pulley the water pump pully and most likely the brackets for the 85 alt. I plan on using the 120 amp mr2 alt and yes the fuse box and wiring has already been upgraded to hold the power. Im ordering the plug for the 120 amp mr2 alt and im away of the charge light fix.is there anything else i need to do the swap? Also does anyone have pictures of there 85-86 setup?
