I am in quest for a heat sending unit for a 1934 320 ci in. Is there a cross number at a napa store?

No cross, the sender and gauge are a single intergral assembly and needs to be serviced as such. You'll need to remove what you have and send to one of the several instrument repair businesses. Many of us have used Wolf Instruments though there are others who do this work.

thank you for the info do you know where to get a sending unit?

As I tried to explain, there is no separate discreet "sending unit", it's all part of a completed assembly and must be serviced as a unit with the dash unit.

If you believe you have a separate sending unit, then perhaps you have some sort of aftermarket gauge and not the OEM unit? Maybe you should post a picture or two so we can see what you're dealing with?

Lonny, there is a pertinent post to this further down the page 'temperature gauge line to head' - with lots of good info and pictures showing what Owen is talking about. If you go through that post, you will be able to glean everything you need. Chris

thank you for all the help when I purchased the 1934 it was in boxes and tubes. I have 800 pictures of how it came apart but no pictures of the motor. the gages are all recondition. I looked at the heat sending unit I can see what you are talking about. The unit is complete. Thank you for all the help
