The problem with the early 40 water pumps was the mounts holes were off location and could,nt be bolted down.Since then they were to be checked before shipping.I just started my 8ba with new water pumps today and seem fine.I was going to buy from speedway and they were on back order,so i bought from hot rod shop and didn,t hear from for about 3 weeks.Then got email saying they would be shipped.I went right away the Speedway and they were in stock.Get this the hot rod shop got them for another place and reboxed and sent to me.So they didn't come from Speedway.My guess they must all be buying from same place.If i were you i'd go with Speedway.
