not sure about rad support
re: blinkers, they are built into the M headlights and there's another 1 on each of the fenders, i actually forgot whether V has blinkers on the fenders. i think it's just a matter of moving the V bumper blinkers to the M headlight ones, might need to extend the wiring i'd imagine.
re: HID, 98% sure they are the same as M35s, i remember checking my mate's v35 cos he was asking what bulbs he had to buy
