I have the SSAC put them on a while back and to get the rear in alls you have to do is rock motor forward and take the Trans dipstick out and they slide right in like no removing the Valve cove no pushing I tried for house and could not get them in. Took the dipstick out and they slid right in. I have about 10 thou on mine so far and I love them. Got the TDC FWI and thing sounds mean as hell now. I thought the same about the price and man they look good in there and they function well.
