Ok.. This is driving me nuts.. Whats the deal? Im trying to get a balancer cover for my 396 and Im having no luck. I already have an 8 inch cover from my 468 project and I ordered a new 6.75 cover and neither one fits. I put a tape on this balancer and its 7 inches dead nuts. Why doesnt Summit or ANYWHERE for that matter make a 7 inch cover?
