I need to buy a new temp gauge for my 1951 1/2 ton chevy truck but I am given two options and I am not sure which one to get.

There is one ranging from 100 to 212 and a second one fromm 100 to 220 and both have the option of eiher 45" line or 60" line.

For those that have been down my road, which one should I get?

Thx
