ACD aye? that box is the closest 8v box you can get to 16v box, ratios are identical apart from 5th which is slightly longer. making motorway driving that bit easier!!in the end i got my box rebuilt. diff rivets had went but luckily it did split the casing. so was happy enough to get an overhaul and the diff bolt kit fitted.how much yoy pay for the flywheel, always wondered just how much of a difference they make to the 16v's
