1961 Willys cj5

1961 willys cj5 with a 1966 dauntless 225 v6 engine. 3 speed manual transmission with a warne overdrive. I have owned this jeep for 21 years and have used it on my ranch and it has been reliable. It will pop out of 2nd gear when decelerating. It has been kept in the barn when not being used and isn't rusted out. I will try and answer your questions but I am not an expert on old jeeps.
