When doing a v8 conversion with the AA kit why do you have to do driveshaft mods and floorboard mods? And what are the dimensions for these changes. Also what are the average prices on the driveshaft mods. I am looking to do this prefferably with the marks of australia but I was offered a complete AA kit for 100 dollars. This sounds too good to be true but if it pans out I would assume it would be worth it from the price angle. If anyone has a negative or positive opinion of this kit I would be greatful to hear it as well as any advice or instruction on installatioin.
