Cheers Andy, by sunk into CP3 and CP4, im guessing you mean the roll bar mounting plates? And then bolting it onto CP3 and CP4? CP3 and CP4 are the large chassis plates with the 4 holes in them and the suspension mount welded onto the bottom.
Oh and yes I will be going for an ali tub, hence why i ordered 2 x CP11 + 2 x SS1 plates from you last week
