i asked that here before and the answers were basicly whatever from a good parts store. well that's what i've always done, but there is alot of cheeper crap around now a days. anyway, the one i got from NAPA fit fine, except the hose fittings were not at the correct angle and i ended up repositioning them a little with help from a large spring on the inside. wasn't hard, just need to make sure you don't collapse or crack something
