O.k., I've got a '46 that's been put onto s10 running gear if that's important. It currently has a heater out of a '56 pickup, if I remember what the previous owner told me correctly. It's started leaking badly, and, as I thought it only worked marginally, I figured this would be a good time to replace it with one that'll run me out of the cab. Does anybody have any recommendations? I don't care about A/c, but the little one (age 2 &1/2 going on 18)

likes to ride in heated comfort, and doesn't understand why we're not driving her "twuck"
