i am new to the Forum and hope that this has not been answered previously and I have just been unable to find the answer. I have a QP 4.7S that has a failed brake booster and needs replacement. I also have a service manual that does not address the brake booster at all. A brake booster is a brake booster, right? Nothing too unusual about it except that from the interior of the car access to the 4 bolts that fasten the brake booster are fairly well blocked. Two on the bottom are accessable without too much difficulty but the two on the top are not. Can someone help or direct me to a manual with the procedure mapped out that shows what minimum number of items I need to remove to access these bolts, please. Thanks.
