I can have the alien cowls with 3.0 and as far im
Aware there is no adaptor plate available only 15" legs from madefi that take 2.5 boxes but they are 2000 dollars each! So was going to strengthen some standard 3.0 legs
Cheers guys its for 3 litre merc same size as 300's etc not the same as a 2 litre/2.5, its really hard to find any 20" legs/boxes for 3.0 mercs i have tried everywhere i can think, i might Have to try in the U.S
