I have a 240 heater valve in ours. One hose had to be routed differently, and I think I had to bend the end of the control cable a bit, but it was all simple to do.

Most heater valves of that era were completely generic internally, the main difference being the orientation of the hose connecting pipes. NAPA sells a repair kit that fixes the internals for $6-$7. It doesn't work every time, but it might be worth a try at that price...

If a '62 is like the later cars, the oil pressure switch is generic, but the temp sender is not -- it's actually part of the gauge, and would have to be repaired along with the gauge as a unit. The gauge does come out of the instrument cluster fairly easily without removing the cluster from the dash.

I just installed a Crane in an early B18 distributor for a customer this afternoon. It does fit. I don't have the part number of the kit, unfortunately -- the customer bought it himself from the Summit Racing catalog.

Don't know anything about a pump for the squirters one way or the other, sorry.
