    1997 GMC K1500 Z71 Oil filter

    Hello, Recently picked up a 1997 GMC K1500 z71. The oil filter is mounted vertically and has no oil cooler lines (I guess the previous owner deleted them). The oil filter is a FRAM PH5, but it hits the front driveshaft. Would going to a smaller oil filter, like FRAM PH30, cause harm...
